Greetings,
I’ve previously run simulations with Dicom files (CT scans) converted to voxel geometry, however, I’m getting a **** Blank common exhausted in Pwxsst **** error now. According to other threads in this forum, I found that it should be related to the maximum allowed number of regions . That makes sense, since the previous simulations were done with smaller tissue parts, however, this time I need a whole human chest geometry included. I have used the Global card and set it to 20 000 (that should be the maximum, right?). Is there a way to go around it (like cropping the voxel file - there’s parts I do not need), or is the error coming from somehere else?
Thank you very much!
Sebastian

yes you can try the following:
- increase the number of regions in the GLOBAL card.
- if needed increase the memory allocated by fluka. This is in what(6) of the GLOBAL card. Unfortunately flair doesn’t offer it as an option so you click the Ctrl-E to manually edit the card.
- last crop your dicom.
- Go the Dicom page, select the CT and go to the View tab
- select with the mouse the region to crop, dragging a rectangle.
- Select also the top and bottom slice and setthem as Zmin and Zmax clicking the button on the ribbon.
- Then recreate the dicom file, it should be cropped.
- Do not forget to click also on the card button to update the coordinates of the cropped voxel file in the input
