This routine is used to initialize relaxation paramter and update bulk viscosity at every time step Bulk visocisty is defined as space-time function to apply ramping and spatial sponge in bulk viscosity
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| real(kind=rk), | intent(inout) | :: | omega(:) |
relaxation parameter |
||
| real(kind=rk), | intent(inout) | :: | visc(:) |
Kinematic viscosity |
||
| type(tem_spacetime_fun_type), | intent(in) | :: | viscSTfun |
viscosity space-time function |
||
| integer, | intent(in) | :: | nElems |
Number of local elements including halos |
||
| real(kind=rk), | intent(in) | :: | baryOfTotal(:,:) |
baryID of total list |
||
| type(tem_time_type), | intent(in) | :: | tNow |
current simulation time |
||
| real(kind=rk), | intent(in) | :: | viscRef |
reference physical viscosity on current level i.e. (dxP_l)^2/dtP_l Dividing physical viscosity with the viscRef gives vL_l/dtL_l |
