Limit on number of entries in region card??

Hello All

I have ran in to a curious problem when using the current develop branch. when i modeled this geometry before with earlier version (i think 0.6.2, using surfaces tag) i didn’t run into this error. Is there any limit on number of entries in region card? i am modelling a MNSR and in the final ring containing 65 rods, when i try to model water between rods, i get an error after 62 surface specifications. if i model it as two semi-circles then it works OK. the input is shown below (only for the particular cells)

after i cross cell 350 when i try to model only cell 2010 and removing surface 3052, i get overlapping cell error.

Thanks for your help

Thanks for bringing up this issue, which I did at one time have in my mind. The problem was that the variable used to read the region specification is fixed-length. As a temporary fix, I’ve extended the length (from 250 characters up to 1000) so if you pull in the latest update on the develop branch your input should now work fine. A more permanent solution would be to use deferred-length characters which were introduced in the F2003 standard, but the compiler we use for testing (gfortran 4.6) unfortunately does not have full support for that feature.

Best,
Paul
