Hello,

 

I hope all is well with you.

 

I am using Nektar++ to solve for Linearized Euler Equations(LEE) using the Acoustic Solver.

 

I have tried to play around a bit w.r.t to the following issues but have been un-successful:

  1. I have found a few tutorials where the solution re-start can be accomplished using .rst file which is supplied under the Initial Conditions field in the XML files. I have made a similar setup for the Acoustic Solver but I get this warning when I run the solver: Fatal  : Level 0 assertion violation m_timestep < 0. This doesn’t seem right because my time step is not less than zero. The .rst file was generated from .chk file of the last time step and, this file was supplied as the file from which the remaining time-steps should start.
  2. Secondly, how can I generate a .bse file? Is this also a .chk or .fld file whose extension has been renamed ?
  3. Is it possible to generate a .bse file with data from an external source ? What would be the right way to approach this ?
  4. What would be the right way to convert 1D Gmsh to Nektar++ mesh using NekMesh ? I have got errors while doing this.
  5. Finally, is there a forum where users can post questions ?

 

Thanks a lot for taking the time to read my email.

 

Regards,
