WELSIM Installation on CentOS 7

WELSIM v1.7 recently announced the support of the CentOS 7 operating system, which is followed by the previously supported Ubuntu and Fedora Linux distributions. CentOS and RedHat users can use WELSIM directly for finite element analysis, while cloud computing users can quickly deploy WELSIM on the CentOS server in the cloud.

Now let’s see how to download, install, and use WELSIM on CentOS 7 for engineering simulation analysis.

Downloading WELSIM

Download the latest WELSIM CentOS 7 version from the website WELSIM.

Installation Steps

After the download is complete, navigate to the folder where the downloaded file is located, right-click on the blank area, and select "Open in Terminal" from the pop-up context menu.

In the terminal window, enter the following command:

$ chmod +x WelSim17SetupCentOS7.run
$ ./WelSim17SetupCentOS7.run

As shown in the picture:

You will see a graphical installation wizard window appear on your screen.

Click "Next", and you will be prompted to enter the installation path. You can use the default installation path.

After clicking "Next", you will be prompted to select the module. WELSIM is a complete CAE simulation solution framework. You can keep the default setting and click "Next".

The installation interface will indicate that it will occupy 423.99M of hard disk space. If you confirm that the computer space is sufficient, click "Install".

After a few seconds, the installation is complete.

Click "Next", and you will see the installation completion confirmation.

Installing Required Libraries

Since WELSIM’s visualization module requires some dependent libraries such as libGL, libGLU, etc., at running WELSIM for the first time, you may need to install those libraries. Use the command below to install the necessary libraries to your system:

$ sudo yum update
$ sudo yum install mesa-libGLU mesa-libGL

As shown in the picture:

Next, open the installation directory and select "Open in Terminal" from the context menu as shown in the figure below.

Type the following command into the terminal window:

$ chmod +x runWelSim.sh  (Only need at running for the first time)
$ ./runWelSim.sh

Using WELSIM

At this point, the main interface of the software will start, as shown below.

Now let’s set the analysis type to steady-state thermal analysis and import a geometric model, as shown:

Set to use the quadratic element and implement the meshing. You can obtain the generated mesh as shown:

Define the relevant boundary conditions as shown below.

After calculation, you can evaluate the temperature result and plot the contour as shown in the figure.

The analysis is complete. Save the project as a ".wsdb" file, which can be opened on this machine or other computers later. The ".wsdb" files saved in the CentOS version can also be resumed in other Linux distributions or Windows versions.
