Problem with thermal analysis

    • javat33489

      Hi all.

      I am conducting a thermal analysis of drilling an SPG ram, using a model from LSTC. The mechanics work perfectly, everything is drilled, the voltages are normal. I want to enable thermal analysis.

      I connect cards:

      I'm using test parameters from my head (HC and TC).


      And INITIAL_THERMAL with a temperature of 22С.


      When calculating, I get the first entry in d3plot and look at it:

      temperature on the drill is 85С


      the temperature on the plate is simply horrid.


      After the start of the calculation I received the following warnings:


      Then I get an error and the calculation is completed:


      Thank you.

      what version of dyna are you using. 

      Any version 14 and higher should be good for SPG-Thermal studies. 

      Cheers, Ram

        I'm using the version from the 2023 kit.

        Tell me which cards should I show you? I would like to solve this error.
