Hello ANSYS Community,

I am trying to apply prestresssing force on a model as thermal load. I have my prestressing strands modeled as line objects and have defined them as reinforcement so they get embedded into the concrete. While trying to apply the thermal load for prestressing force, I get the error "The load cannot be applied to bodies where Model Type behavior is set to Reinforcement." How can I address this issue? I am using ANSYS Mechanical, static structural, 2023.

Thank You.

Perhaps that's a limitation of the Mechanical gui.  From the ds.dat file can you determine what element type is being used to define the reinforcing?  For example, REINF264.  The APDL element documentation indicates structural temperature is a supported load for REINF264 and the element has the material property ALPX to support thermal strain.  If it's just a gui issue a commands object would be a way to apply the thermal load.

Hi, 

Thank you for the response, 

I am not familiar with using commands object. Can you please tell me how can I learn to use it? 

 

Thanks,

You could start with these commands in a commands object:

esel,s,enam,,264   ! select the reinforcing elements

elist                        ! list them to find out their material number 

alls 

/eof                        ! remove this command after reviewing the elist output

mp,reft,nnn,200     ! nnn is the material number you found from the elist command.  200 is the stress free ref temperature
