Lift the mean on the face to a positive value if necessary.
In some equations, some variables may not be allowed to be negative, for example the density and energy in flow simulations. With this routine we enforce this limitation for the projected mean state on the element surfaces.
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| integer, | intent(in) | :: | nElems_fluid |
Number of fluid elements |
||
| real(kind=rk), | intent(in) | :: | volState(:,:,:) |
Volumetric modal states for each element |
||
| type(atl_faceRep_type), | intent(inout) | :: | faceRep(:) |
Modal representation on the face that might need limiting. All means below 0 of variables where positivity is to be ensured will be increased to a small value above 0. |
||
| integer, | intent(in) | :: | nScalars |
Number of variables |
||
| logical, | intent(in) | :: | ensure_positivity(:) |
Indication for each variable, whether positivity is to be ensured or not. Only variables where this is set to .true. will be modified by this routine. |
