[FLASH-USERS] problem with LaserSlab

[Hansen, Eddie]

Hello,

Your setup command has some typos in it and might be incomlete:

  1.
it should be -nxb=16 -nyb=16 -nzb=16, not -nbx -nby -nbz
  2.
spherical geometry would be "+spherical", but this doesn't work in 3D anyways, so you can remove that.
  3.
many HED sims, especially those with +laser, will want multi-group radiation diffusion and more than one species (usually at least one for a target and one for chamber)  with different EOS and opacity options avaible. For all of that (with 6 radiation groups), you'll want "+mtmmmt +mgd mgd_meshgroups=6 species=targ,cham". This is a commonly used set of options. Also, looks like your specific problem might use 'au' instead of 'targ'.

Your specific error is probably occuring because the typos described above are causing the setup script to skip the other options you've specified.

Subject: [FLASH-USERS] problem with LaserSlab

Dear Flash developers and users,

I'm a newbie Flash user, and I'm having some troubles.
I installed FLASH4.8 and tried to compile the basic Sedov problem. It works and in the object folder I have the flash4 file, then it correctly run the simulation.

However, when I try to do the same with LaserSlab I have an error message. I'll explain everything below.
1) ./setup -auto LaserSlab -3d -nbx=16 -nby=16 -nbz=16 -spherical +laser +uhd3t +hdf5typeio species=au

2) the object folder is correctly created and so I run make into it. After few minutes I get the following error message:
143| ed_cellTele (i,1,1) =blockData (TELE_VAR,i)
Error: Symbol 'tele_var' at (1) has no IMPLICIT type
make: *** [Makefile:132: ed_bloclData1DRec.o] Error 1


How can I solve this problem?


Best regards,

Vittorio Ciardiello
