Hi,<\/p>\n

I’ve created Coupled Field Transient project and I want to import heat generation from a file. When I did it in Thermal Transient it looked like this:<\/p>\n

<\/p>\n

but now i don’t see this option:<\/p>\n

\"\"<\/p>\n

The file which I use looks like this:<\/p>\n

<\/p>\n

<\/p>\n

Is it related to the physical area where I only have structural and thermal analyses? I was reading this website: https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v231\/en\/wb_sim\/ds_imported_loads.html and see that only Steady-State Thermal, Transient Thermal, Thermal-Electric can import heat generation. Is there any way around this?<\/p>\n

Also, I have a question about orthotropic ICTE. I’m not sure if I’m using it correctly. I want to define material conditions that cause the body to expand only when the body temperature is between 80 and 120 degrees Celsius, so I defined it like this:<\/p>\n

\"\"<\/p>\n

I was reading this presentation: https:\/\/www.padtinc.com\/2017\/07\/11\/secant-or-instantaneous-cte-understanding-thermal-expansion-modeling-ansys-mechanical\/ and I don’t understand why when I define a coefficient of 0 at some temperatures it is wrong. When I use this equation:<\/p>\n

<\/p>\n

it doesn’t mean that when coefficient = 0 the strain is 0? I will be very grateful if someone explain it to me. Maybe is there a better way to define exansion only between some temperatures?<\/p>\n

 <\/p>\n

Best regards,<\/p>\n
