Elmer Discussion Forum

Hi Kumar,
The problem persists with the latest LTS version of Ubuntu.

However, the fault disappeared when I used the following codes in accordance to Elmer Models Manual But looking at the source code of FlowSolve.F90 - lines 825-847, there is no keyword Porous Resistance and thus it can be concluded that this will yield Pwrk as null matrix , and effectively drag = 0 (that is no calculation of the effects of porous resistivity). So, either Porous Resistivity should be entered as real array Porous Resistivity (i,j) or Porous Resistivity i, i=1,2,3 must be entered as real number in the solver input file. This again renders the same question which you put at the beginning. This can just be a notification to Elmer Team to edit the list of keywords in Elmer Models Manual.

Yours Sincerely,
Anil Kunwar

Thanks very much for your effort, Anil. It should then work with my Elmer-8.3 on Ubuntu 16.04 LTS.
