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
Code: Select all
...
Porous Media = Logical True
Porous Resistance = Real 1.02345
...
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
