Hello everybody.
Two questions:
1- Is there somewhere an example of using the Amplitude function?
2- Is it possible to do a conditional simulation, that is to say for example a thermal simulation during which a temperature at a point reached would modify a boundary condition?
Here for dynamic analysis in time domain: https://www.youtube.com/watch?v=R8HQKI3PTrI
No, this would require Fortran subroutines. They are described in chapter 8 of CalculiX User’s Manual: http://www.dhondt.de/ccx_2.21.pdf
Temperature-dependent material properties can sometimes serve as a workaround in such cases.
First try to understand how amplitude work.
Then , you can do a first analysis to find when do you reach the desired temperature.
Prepare an amplitude such that it is 0 up to that time and then 1 from there. Assign that amplitude to the variable you want to turn on at that precise time step.
Thank you very much!
Very good idea! THANKS!
