Defining SPC temperature for transient heat transfer analysis in HyperMesh 2024.1

Damla

Hi, I am performing a transient heat transfer analysis in HyperMesh 2024.1. I have x, y, z, temperature data that I want to map using a Field. How can I define this in a time-dependent way?
I am creating this thermal boundary condition with an SPC Card. However, when I try to define the SPC Card within the time step input for a transient analysis, I encounter problems. In the EXCITEID section, I add the load collector that contains the SPC card generated with Field. For the Type option, when I choose either LOAD or TEMP, I get errors in both cases.
If I create the thermal boundary conditions defined by the Field using TEMP card, then I do not get an error in the load step input. However, in that case, the TEMP card shows no effect at all in the analysis results. Could you please help me with this? Thank you in advance.

Hi @Damla ,

Please find my answer below.

For your transient temperature case, the TLOAD1 must be excited by the SPCD entry, and the Type should be defined as Displacement. Alternatively, this can also be achieved by using a combination of a TEMP load, in which case the Type should be defined as Load.

For your reference, I’ve attached a sample model.
