Hi Peter,

Thanks a lot for the reply. Can't wait to use Elmer with PetSc if it's available in the near future.

Hi all Elmer User,

Can we use Elmer FEM with PETSc(Portable, Extensible Toolkit for Scientific Computation) package? The following link describes PetSc's capability:

Hope to hear some answers soon. Thank you.

Hi all Elmer Users, At the moment, I am trying to run the fluid-structure interaction testcase "Fluid Flow Around Elastic Beam" with h-adaptive. The following are the fsi.sif file: Header Mesh DB "." "fsi" End Constants End Simulation Max Output Level = 3 Coordinate Sys...

Hi, Thank again Peter for your answer. As usual you insights did help increased my understanding of Elmer codes. At the moment, I am using: 1) HeatSolver (L-shaped p-adapt) 2) FlowSolver and ElasticSolver for the FSI testcase I noticed that only FlowSolver are at the moment capable to be used with p...

Hi, Thanks Mika for the response. This really provide much more insight on the construction of p-element in Elmer. Can you give me some advice on which part of the code requires changing to include the effect of high order p-element on the heatsolver? For your information, I've already changed the p...

Hi Peter, Thanks again for helping. If I am not mistaken, the use of "303p2" or "303p3" did utilize 303 linear element(303 + p + order of the p-element)..so in my case the implementation of high order element should be correct up to my knowledge( correct me if i am wrong) . Also,...

Hi, Thanks Peter for the advice, however, it is still unable to compute the heat problem for high order element. The following are the result for 1st order and 2nd order element: 1st order without "Element = p:2" keyword HeatSolve: Result Norm : 4.77841054713980112E-002 2nd order "Hig...

Hi,

Thanks Peter for the quick answer. Already tried the method you've suggested ,however, the following error appears in test.log, do you know why this error occurs and how to solve it?
tq...

Hi all Elmer User, I've been trying to increase the order(p) of element using high order element however it seems that there's no change in the value of the T1: res energy norm. The following are the mesh.elements file for p- high order elements of order 2: 1 1 303p2 4 5 1 2 1 303p2 2 1 5 3 1 303p2 ...

Hi Peter,
thanks a lot for a prompt answer..its a bit unfortunate to hear this..i am thinking of implementing it myself then..but is a bit unsure whether it will be a success..hope for the best then
