Why did you choose SIMULIA? First, Abaqus is powerful and can solve most structural problems. Second, fluid-structure coupling is convenient. STAR-CCM+ comes with a case that shows you how to couple with Abaqus bidirectionally. Third, it is the inertia of past experience. After all, automobile companies use Abaqus a lot, and there are a lot of cases and resources.

1. Preparation

First install the development environment and some necessary software:

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.

1. Related commands

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:
