Consider installing Linux on a new computer, not a dual system, because it also needs to meet daily office work. If you don’t like to mess around, you can use WSL, which is implemented using Hyper-V, and at the same time, you can access the virtual machine through port mapping.

2. Preparation

2.1 Download Ubuntu

I am a CFD, so I naturally cannot do without Fluent. This thing is a distribution version. Confirm which distribution is supported from the official website information, and install which one is supported, so as not to reinstall the system later.

Recently, I often do some cold plate structural analysis, involving thin plate modeling. Although I have tried to use Shell units for analysis, the stress and displacement results of Shell units are larger than those of Solid units, and it is more likely that the calculation will not converge when it comes to contact problems. Fortunately, Ansa provides a way to generate a body mesh by stretching Shell units, which can quickly generate a Solid mesh through Shell units, greatly saving modeling time.

In Ansa, the following commands are commonly used to set contact for Abaqus:

2. Contact pair

The most commonly used contact pairs are generally created by calling up the creation dialog box through AUXILIARIES → CONTACT → CONTACT .

Common settings are generally as follows:
