[Help] How to set the interface between ANSYS and UG?
I would like to ask you prawn, I have set up the ANSYS and PRO-E interface, can you set up the UG interface? If so, how do you ask? Hope you prawn pointing! !
In UG, EXPORT selects PARASOLID, the output is in text format, and then input in ANSYS to set the version number and path of ANSYS in the UG environment file. In AN, the ANSYS analysis engine can be called; in ANSYS~/ANSYS57 /ac4/bin set UG parasolid version can be directly read into the UG part file can convert the graphics in UG18 into 11-16 version can be read out with ANSYS, I do not know what you said "in ANSYS ~/ANSYS57/ac4/bin sets the parasolid version of UG to read directly into the UG part file" How to achieve it? Please give pointers.
~/ANSYS57/ac4/bin only ug170 folder, which means only support the 17 version of the following UG parasolid, this time you can add ug160 folder, the ug170 content completely copied over, you can directly read the ug16 part , but higher than the 17 version may have problems ~
Can try to open UG18 PART in this way, I have not installed UG18, so I have not tried it, but the low version will generally have problems in supporting the high version [Help] How to input I-DEAS model file in ansys6.0 In ansys6.0, select Import---IDEAS to display a dialog window. How to lose the last line?
I have never used this interface, but I have successfully imported the finite element model of ideas into ansys, as follows:
Create a model in ideas, divide the grid, use the export in ideas, there is an option in the inside, select it, then directly resume in ansys. [Repost] ANSYS and ADAMS interface [Essence]
ANSYS and ADAMS Introduction ANSYS software is today's most famous finite element analysis program. Its powerful analysis function has been widely accepted by the global industry and becomes the CAE software supplier with the largest user group. Its characteristics such as multi-field and multi-field coupling analysis, multi-physics optimization, unified database and parallel computing all represent the development trend of CAE software.
ADAMS software is currently the most authoritative mechanical system dynamics simulation software. By creating a virtual prototype on a computer to simulate the entire motion process of a complex mechanical system, the purpose of improving design quality, saving cost and saving time is achieved.
Through the bidirectional interface between ANSYS software and ADAMS software, the influence of flexible body parts on the motion of mechanical system can be easily considered, and the results of stress and strain analysis based on accurate dynamic simulation results are obtained to improve the analysis accuracy.
Interface Background ADAMS/Flex software allows flexible body components to be created from modal frequency data in the ADAMS model. Flexible body components can have a significant impact on the motion of the mechanical system. Considering the effects of flexible body components in the ADAMS model can be greatly improved. Simulation accuracy, while the ANSYS program provides a convenient way to create flexible body parts.
After generating the finite element model of the flexible body part, the ANSYS program can easily output the modal neutral file jobname.mnf required by the ADAMS software by using the adams.mac macro command. This file contains all the information of the flexible body in the ADAMS. Read the file directly in the ADAMS software to see the model of the flexible body part. Specify the way the flexible body is connected with other parts, and apply the necessary external load to the system to simulate the dynamics of the system.
When to use the ANSYS-ADAMS interface In a mechanical system, the flexible body will have an important impact on the motion of the entire system. If the influence of the flexible body is not considered in the kinematic analysis, a large error will be caused, as well as the entire system. The motion condition, in turn, determines the stress and motion state of each component, which determines the stress-strain distribution inside the component. Therefore, if you want to accurately simulate the motion of the entire system, consider the effect of the flexible body component on the motion of the system, or Based on accurate dynamic simulation results, stress and strain analysis of flexible bodies in motion systems requires the use of ANSYS and ADAMS software.
Analytical Procedures The complete steps for stress-strain analysis of flexible body components in a motion system using ANSYS and ADAMS interfaces are as follows:
Establish a finite element model of the flexible body part in ANSYS software and use the adams.mac macro file to generate the flexible body modal neutral file (jobname.mnf) required by the ADAMS software;
Establish a rigid body model in the ADAMS software, read the modal neutral file, specify the connection method between the components, apply the necessary load for system dynamics simulation, and output the load file required by ANSYS after the analysis is completed ( .lod file), this document records the motion state of the flexible body and the load it receives during the movement;
In the ANSYS program, a stress at a corresponding time in a load file is applied to a flexible body to perform stress-strain analysis on the flexible body.
Generate flexible modal neutral files (.mnf files) used by ADAMS software in ANSYS software
Enter the ANSYS program, build a model of the flexible body, and select the appropriate unit type to divide the unit. There must be a node at the center of rotation of the flexible body (coupling with the rigid body). This node will be used as an external node in ADAMS. If the flexible body is hollow at the joint, create a node here and use it. The rigid area handles this node (external node) and its surrounding nodes. Select the external node and run the ANSYS program macro command ADAMS to generate the modal neutral file (jobname.mnf) required by the ADAMS program. Pay attention to the following 4 points in this process:
Unit system, since different unit systems can be processed in the ADAMS program, the MNF file must contain the unit information used by ANSYS analysis. Therefore, before running the macro command ADAMS, you must use the command /units to specify the use in ANSYS analysis. The unit system is SI, CGS, BFT or BIN. If you are not using the above four unit systems, you can use the following command:
/units,user,
Among them, L, M, T, F are the conversion factors of the SI unit system and the unit system used in the ANSYS analysis.
The external node, the external node is a noun in the ADAMS software. In the ANSYS program, the node at the joint position of the flexible body and the rigid body is used to connect the flexible body and the rigid body in the kinematic analysis performed by the ADAMS. Generally speaking, a joint position uses only one node as an external node. If the joint of the flexible body is hollow, a node is created at the joint as an external node, and the external node and the surrounding flexible node generally use a rigid region. definition.
Before running the ADAMS macro, only the node that will be used as the external node is selected. Only the node that is the external node is selected before running the macro command ADAMS, because the ADAMS macro will treat the node selected at this time as an external node, so this selection step is indispensable.
Run macro ADAMS, _NMODES generates the modal neutral file required by the ADAMS program. The modal neutral file. MNF contains information such as the mass, centroid, moment of inertia, frequency, mode shape and participation factor of the payload.
Download an example of generating a modal neutral file in ANSYS (Word document, right click to download).
"In the ANSYS program, stress is applied to the flexible body by applying a load at the corresponding moment in the load file to the flexible body."
How can I talk about the specific operation?
Parametric Programming Language (APDL) These commands can be written into a program written in the programming language. The parameters of the command can be assigned values, or they can be assigned by the result of the expression or the parameters. From the function of the ANSYS command, they correspond to the definition of the geometric model, the division of the cell grid, the material definition, the addition of loads and boundary conditions, the control and execution of the solution and the post-processing calculation results in the ANSYS analysis process.
This is convenient with the Parametric Programming Language (APDL).
Generate the payload file (.lod file) required by ANSYS in the ADAMS software.
Enter the ADAMS program, establish the rigid part of the mechanical system, read the modal neutral file .mnf to establish the flexible body model, specify the connection mode between the flexible body and the rigid body, and define the load and boundary conditions for the mechanical system movement according to the actual situation. Learn to analyze. After the analysis is completed, the load file (.lod file) required by the ANSYS software is output. This document contains information such as the motion state of the flexible body and the load it bears at different points in time during the movement (eg force, moment, acceleration, angular velocity and angular acceleration).
Download the load file example generated by ADAMS (Word file, right click to download), where nodes 1301, 13000 are the external nodes of the flexible body, which is the connection point between the flexible body and the rigid body.
