here trying to solve the pde: ut + ux = 0 in acefem. I have two questions regarding tangent and residual.
Tangent shows the
s$$and residual showsp$$in the acefem code. There are two parts comes underp$$ands$$which are connected throughp$$, "AddIn" -> Trueand s$$, "AddIn" -> Truerespectively. Here I could not able to understand that what does this ""AddIn" -> True" does to thep$$ands$$? Does it shows the direct addition of first part and second part ofp$$?- How exactly SMSStandardModule["Tangent and residual"] works in acefem. I have already checked with acefem help in mathematica. It seems to me that it operates upon default standard user subroutine for tangent and residual. If yes then I would like to see that how does the subroutine looks and works. I also checked the default acefem codes for solving the pde with finite element method. There, by directly using SMSStandardModule["Tangent and residual"] will gives the solution. But in the case of above mentioned pde, I need to provide each entry of
p$$ands$$manually. So is there any way to createp$$ands$$automatically?
Your suggestion's to make it automaticlly would be helpful to understand the concept. Thank you.
