I was performing a simulation at Comsol and recently I needed to have a time a step of 10^-8. I would like to know how to achieve such a value without any occurrence of error.
Thank You
Hi
If you mean to determine time-step, you can define it in "Output times" section in "Study setting" of a "Time-Dependent" study with the following format:
range(starting point,time-step,endpoint)
But if you mean how to avoid occurring error in this time-step, you can decrease "Relative tolerance" in the mentioned setting or discretization order in the interface setting. But with suitable meshes, you will not need these actions.
Amin Ghaffarzadeh Bakhshayesh thank you for your answer but however I have already used the range but however I would like to increase the accuracy and reduce the error of my simulation. Even if I use a 10^-7 step range I would like to add more accuracy into my simulation.
