Hi,

Therm 7.8 is not allowing me to run the calculation. Initially I will get the following message:

Then this, after increasing the Quad tree mesh:

Can someone help, or advice?

In this situation, you generally need to simplify your model in order to allow THERM to mesh it.

I will take a look at your file and see if I have suggestions about how to simplify it.

There are a lot of points that don't really need to be in the model, particularly when defining curves. I deleted lots of points in curves that won't affect the results but which eventually allowed the model to mesh.

I also shortened the height of the concrete element, because it didn't need to be that tall to model the thermal effects and having a "tall" model can make it harder for THERM to mesh it.

The attached model now simulates

This model was created using THERM 7.8.74. I don't know what version you are using, but if it is an earlier version, you probably can't open the file I created.
