But the Fluent crashed when the code runned with the error &#8220;999999:mpt_accept:error: accept failed: No error&#8221;. I think there may be two questions:&lt;br&gt;1 how to access the solid temperature in the fluid zone and fluid temperature in the solid zone?&lt;br&gt;2 how to specify the UDS Scalar as the energy source (Figure 2)?&lt;br&gt;Could anybody help with this?
