Hi Everyone,
In COMSOL Multiphysics, I am performing a parametric sweep for finding the solution. The study is time-dependent. I have one parameter named temperature whose value is 333, 343, 353 (K) and another parameter is time whose value is 1, 2, 3 (hours). I want to obtain the value of dependent variable u in the following manner
for 1 hr at 333K (total of 1 hour)
for 1 hr at 333K and 1 hr at 343 K. (total of 2 hours)
for 1 hr at 333K,1 hr at 343 K, and 1 hr at 353 K. (total of 3 hours)
So basically I want to have the value of u at each temp for 1 hr. And the initial condition at another temp should be the final value of u obtained at the previous temperature.
Thank you in advance.
Looking forward to your help.
Dear Abhishek Yewale,
under the settings of the study you can find the window "Values of dependent variables". Here you can select how the solver choose the intial values in "initial values of variables solved for". By default, the setting "Physics controlled" is selected. In your case, use "User controlled", in "Method" choose "Solution", in "Study" search for the study that you are interested (in your case the study containing the solution of the previous computation) in and in "Selection" you want the last step solved.
Hope this will help,
CA
Thanks a lot for your reply Ciro Alberghi . I will try this as you have explained.
you can define several steps for your study so the answer of first step will be the initial value for the next step.
or you could define the variable you want to be read from a previous study that has been done.
Please, send me the mathematical equations describe your physical problem with initial and boundary conditions. Then, the way of solution is determined and adjusted.
Dear Ciro Alberghi,
I have tried to do the required as you have advised. But I am stuck in ' Values of dependent variables' while defining solution (what should I choose out of solution, parametric solution) and time. I have attached the pic below. I am not sure how to proceed ahead. Please help me out.
Dear Hiwa Aryan
Will you please elaborate more on your point. I didn't understand well.
