Hi,
CST setting ensures that time step is not less than user-defined value but it does not make time step smaller.
Is there another way to reduce the time step except making mesh size small?
Thanks
You can use the engine option,
/DTIX to manually set a initial and maximum time step for Radioss such as,
/DTIX
1e-9 1e-9
Another option is to reduce the time step scale factor from the default value of 0.9 to say 0.1.
/DT
0.1 0.0
Thanks,
Andy
Thank you so much
