Beam2DThermalAction #7

Open qc112233 opened 5 years ago

qc112233 commented 5 years ago

Hi all, I'm working on a 2d model with temperature variation. The approach A.In-line temperature definition 2D model works perfectly fine but approach B.Using external temperature data file cant apply the temperature load. I wonder how thermal action should be correctly added? The WARNING I get is: "invalid T1 -source for -beamThermal" Thank you for your help Cheers qc

Hi shakalaka Can you please show your input command? External temperature data file works well for me.

Cheers Mian

Hi Mian I download the example from the web and use the approach of external temperature data file, but failed. Could you send me some examples, it will be helpful. Thank you! Attached is the source file.

Cheers

Hi qc The external temperature data file has to give all 9 temperature points across the section. Please see the file I modified to make your model work attached in this email.

Cheers, Mian

Hi qc I can run your model and get results with no problem. This is strange. I attached the input files I used.

Cheers Mian

@MianZhou Hi Mian, I am having the same issue but I'm unable to access the input file you shared with qc. Would you be able to share the file in the github thread? Thank you!
