ANSYS

ANSYS softwareIt is a large-scale general-purpose finite element analysis (FEA) software developed by ANSYS Company in the United States. It is the fastest growing computer-aided engineering (CAE) software in the world. It can interface with most computer-aided design software to realize data sharing and exchange, such as Creo , NASTRAN, Alogor, I-DEAS, AutoCAD, etc. It is a large-scale general-purpose finite element analysis software that integrates structure, fluid, electric field, magnetic field, and sound field analysis.ANSYS official version It is widely used in nuclear industry, railway, petrochemical industry, aerospace, energy and other fields.

Ansys function introduction:

3. Continue to develop and provide world-class solver technology.

4. Provides multi-physics coupling solutions for complex simulations.

5. Integrate the grid technology of ANSYS and generate a unified grid environment.

6. Efficiently solve large-scale problems through support for advanced software and hardware platforms.

7. Continue to integrate advanced computational fluid dynamics technology.

8. Continue to improve the best CAE integrated environment-ANSYS WORKBENCH.

ansys installation method:

1. After downloading ANSYS from this site, use 360 ​​compression software to decompress it, and copy the download address in the TXT text to the browser. After the download is completed, double-click the .exe file to enter the software installation agreement interface, check [I Agree], and then Click [next].

2. Select the ANSYS installation location. You can click [browse]. In the window that opens, you can select the software installation location. After selecting, click [next].Note: All installations require about 10G of space, and sufficient space is required for installation.

3. When asking for the license server name, enter localhost (without quotation marks), copy localhost to hostname, and click [next].

4. Select the program to be installed by ANSYS. You can choose it yourself. Click [next] after completing the selection.

5. Check skip (this step is to associate with other CAD products) and click [next] to start the installation.

6. Prepare to install ANSYS, click [next].

7. ANSYS is being installed, you need to wait patiently for the software installation to complete.

8. After the installation is completed, return to the main interface and start installing "ANSYS License Manager". Just follow the prompts to complete the installation (after the installation is successful, check the menu for new items)

How to use Ansys

How to export command flow in Ansys

1. We first open the Ansys10.0 software on the computer. We first build a cuboid model (I don’t need to explain how to build it specifically), and then the editor will show you how to flow the commands of this cuboid. Come out and run these command flows quickly.

2. In the menu bar above the main interface, click the [List] option, and then in the pop-up window, select [Files] - [Log Files] in sequence.

3. At this time, the command flow window will open. Pull the sliding button on the right to the bottom and find the bottom of the page.

4. Then we find the command flow we need in the page window:

/PREP7

BLOCK,0,3,0,1,0,3,

All the previous data are not needed, only these two items are enough. "BLOCK,0,3,0,1,0,3," is the data to create a cuboid. Then select them and press [Ctrl+C] on the keyboard to copy.

5. Then we create a new txt document on the computer and paste the data we just copied into it. As shown below. By analogy, in each subsequent step, copy and paste the corresponding command into the txt document, and then save it.

ANSYS FAQ

How does ansys use the import command flow to return to the previous step?

1. When we make an operation error, Ansys does not have a button to undo the operation. At this time, we can use the command flow saved before importing to return to the previous step. First, click the [File]-[Clear&star New...] option in the menu bar.

2. Then in the pop-up prompt window, click the [OK] button, and then click the [Yes] button.

3. All data will be cleared. Click the [Ansys Command Flow] input box above, and then paste the command flow that needs to be run.

4. Then press the [Enter] key on the keyboard to quickly obtain the previous operation, eliminating the trouble of re-operation.

In nonlinear analysis, how to judge convergence based on Ansys trace display?

In the ansys output windows, there is a force convergence valu value and a criterion value. When the former is smaller than the latter, a convergence is completed. You can check it yourself. The meanings of the two lines are:

1.F L2: 2 norm of unbalanced force

2.F CRIT: Convergence tolerance of unbalanced forces

If the former is greater than the latter, it means there is no convergence and the calculation needs to continue. Of course, if you use the bending moment M as the convergence criterion, then it corresponds to M L2 and M CRIT

Which one is better, abaqus or ansys?

To get started with CAE, choose ansys. Ansys is considered the veteran large-scale finite element software. It has many functions and can meet many applications. Especially after the acquisition of Fluent and Ansoft, it should be very powerful in the fields of fluids and electromagnetics. ANSYS is more academic, while ABAQUS is more engineering. ABAQUS is currently a software with strong nonlinear calculations. It is better than ANSYS in structural calculations, but it does not have a fluid module, so it cannot do fluid calculations. Another software with strong nonlinearity is ADINA, which has both structural and fluid analysis modules. It is currently the most powerful software. Good fluid-structure interaction analysis software. Abaqus is not as easy to get started as Ansys. However, after being acquired by Dassault, it is also developing into multi-functional products. It is very non-linear and cannot be compared with Ansys.
