Re: New source routines in update 2.1.4

Hi,

that's correct. Type 2 just sets the time coordinate of the neutron to zero and assigns equal weight of 1.0 to each of the source points. With type 2 you should be able to use the Serpent generated source files as an initial source for a dynamic calculation without setting these yourself.

Re: Writing source files

Hi Jesse, do you get output during inactive cycles when you are using the "det" or "set csw" option? In both case that behavior is a bit unexpected and I can't seem to reproduce it with a simple input. For "csw" the check should be already at fission.c Lines 348-350 of fission.c should be if ((RDB[D...

Re: Problem about Sab thermal scattering

Hi,

The problem is caused by the forwardslash character / in the second thermal library name. Putting that name in quotation marks should fix the problem e.g.

Code: Select all

therm zrh390 zrh.39t  %line15
therm zrh400 "zr/h.11t" %line16

Re: volPower with OpenFOAM interface

Great,

good to hear that it seems to be working. The volumes are also printed in the matlab-output mode (giving an output filename ending with .m), but the fprintf-statements can be also modified to give easily parseable output.

Good luck and have fun,

Re: volPower with OpenFOAM interface

Hi Jesse, can you try to compare the power distributions without volume normalization on the interface output. Just switch line 355 from printinterfaceoutput.c from fprintf(fp, "%12.5E\n", 1E+6*Mean(ptr, i)/vol); to fprintf(fp, "%12.5E\n", 1E+6*Mean(ptr, i)); If your mesh has cells that are of diffe...

Re: search function is not good

I readjusted the common word treshold and rebuilt the search index for the forum. Searching seems to work now.

Re: Geometry plotting error (no cell)

Hi Tobias, I think you are correct in our reasoning that the lattice definition is not big enough to fill the whole area inside surface "systemBoxInner". However, it seems to me that your new lattice is still not big enough. You can see the green areas in top left and bottom right parts of the _geom...

Re: Multi-physics interface

I wrote a small hotfix to enable the usage of material files with the OpenFOAM interface. It seems to work, but there might be some unexpected behavior. I'll send it to you by email for testing.

Re: Multi-physics interface

Jesse, providing a separate material-file to link the cells with materials is currently not available for the interface. It would, however, be very useful and since some of the needed routines are already available in the unstructured mesh based geometry generation, this is probably something that w...

Re: MSR1 example

Based on the negative sign of kT, Serpent is still receiving a negative temperature from ifcpoint.c. I tried the msr1 example with my fresh 2.1.21 version and got the same error as you: Fatal error in function GetTemp: Error in temperature (fuel) 1.192400E+03 9.029910E+02 Simulation aborted.
