Description
Description
A user-defied inlet velocity profile can be specified using
<Add_BC name="left" >
<Type> Dirichlet </Type>
<Time_dependence> Steady </Time_dependence>
<Profile> User_defined </Profile>
<Spatial_profile_file_path> vel_profile.txt </Spatial_profile_file_path>
<Value> -100 </Value>
</Add_BC>
However, the solver fails with
[svMultiPhysics] ERROR: The svMultiPhysics program has failed due to unhandled exception.
FSILS: A zero matrix norm has been computed. This is probably caused by ill-posed boundary conditions.
Reproduction
Run a CFD simulation with a user-defied inlet velocity profile
Expected behavior
A CFD simulation with a user-defied inlet velocity profile should work.
