I want to import and analyze temperature distribution data from other software.

Question

I am using Creo Simulate Release 6.0 and Datecode6.0.4.0
Thank you for your help.
Please advise how to set boundary conditions for creo simulate.Is it possible to input boundary conditions such as temperature and pressure by mapping from other analysis results?
We are using another company's thermal fluid analysis software, and would like to reflect the results obtained from fluid analysis in stress calculations.For example, structural analysis takes into consideration the pressure distribution inside a storage tank.
Aside from inputting the results of another company's thermal fluid analysis software, is it possible to set boundary conditions that take into account arbitrary distributions?

I am using Creo Simulate Release 6.0 and Datecode6.0.4.0お世話になります。creo simulateの境界条件設定方法についてご助言ください。温度や圧力などの境界条件を他の解析結果などからマッピング入力する事は可能でしょうか？他社さんの熱流体解析ソフトを運用しており、流体解析で得られた結果を応力計算に反映したいと考えています。例えば、貯蔵タンク内の圧力分布を加味した構造解析です。他社さんの熱流体解析ソフトの結果を入力するかは別として、任意の分布を加味した境界条件の設定は可能でしょうか？

Yes! High Difficulty.

I wrote some code to parse and translate Nastran format CFD pressure to PTC Neutral file format.

Nastran/Optistruct *.FEM output pressure map.

External thermal distributions also in similar way.

Easier to do thermal temperature distribution analyzed in Creo thermal then transfer to Creo structure. (like for CTLE stress analysis)
