Hello,
I am trying to simulate two hollow pipes, that touch at 1 face, under the influence of a constant temperature field, for a designated amout of time. I would like to achieve a transient result, where I can observe the expansion the pipes experience. Main concern is two pipes are made out of different materials. For example steel and aluminum.

The Question is:

In solids4foam it is possible to define the mechanical propeties for two different materials and assign them to geometries.

However I am not able to figure out, how to assign different thermal properties for different materials.

• I am using OpenFOAM v2012 and the latest version of solids4foam in WSL 2.

If you have a solution for it I would be glad to hear.

With kind regards

Yes, in solids4foam, you can give each pipe its own thermal properties (like thermal conductivity and expansion) — even if they are made of different materials like steel and aluminum.

To do this:):

Make sure each pipe is a separate solid region (like "pipe1" and "pipe2").

In each region’s folder (constant/pipe1/ and constant/pipe2/), add a file called thermophysicalProperties.

In that file, you can set different thermal values for each material.

Just like you set different mechanical properties, you do the same for thermal ones — but in the right folder for each pipe ;).
