Hi Lisa, I think that step-44 applies the type of boundary condition that you are describing here. Regards, J-P On Thursday, October 13, 2016 at 11:47:02 AM UTC+2, Lisa Collins wrote: > > hi, > I forgot t

[deal.II] Solution Components of a Vector valued problem

Hello, Dealing with vector valued problems in deal ii is a bit confusing for me. I have a question regarding the solution vector (S). If we have a problem with 20 nodes and 3 dofs per node (u_x , u_y , and T temperature) can we always say that: S[0] = u_x of node A S[1] = u_y of node A S[2] = T

[deal.II] Output parameters other than DoFs

Hello, I solved a typical pressurized cylinder problem with a hot pressurized gas inside it. I can plot u_x , u_y , and T (temperature) but in this vector valued problem I do not know how to output below values: 1- u_r 2- sigma_xx, sigma_yy 3- sigma_rr , sigma_tt Thanks Lisa -- The deal.II p

hi, I forgot to mention that I want to implement the pressure BC in a vector valued problem. a cylinder with a hot pressurized gas inside it. Best regards. Lisa On Thursday, October 13, 2016 at 11:27:08 AM UTC+2, Lisa Collins wrote: > > Hi, > I just would like to implement a simple constant pres

[deal.II] Re: Pressure BC

Hi, I just would like to implement a simple constant pressure BC for a solid material in the referential configuration. Pressure is constant and independent. I want to model a pressurized cylinder. Thanks. Lisa On Wednesday, October 12, 2016 at 1:39:33 PM UTC+2, Jean-Paul Pelteret wrote: > >
