Hi, I have a question. What I would like to do with galprop is that I want to propagate HE electrons within small 3D space placing SNR sources. I have downloaded v50p, and I am able to run galdef_50p_999726 without any problem. Then, I have changed a few options (especially n_spatial_dimentions = 3 and be careful with not blowing up memory.) in galdef file. I have played around with different parameters and gives me always the following message with segmentation fault in the end.

After experiencing the same problem I traced the error back to line 44 in D_xx.cc. The problem is that regardless of the value of n_spatial_dimensions the array Dxx.d2[ir][iz].s[ip] is filled.

If the user specified n_spatial_dimensions = 3, Dxx.d3[ix][iy][iz] will be created rather than Dxx.d2[ir][iz]. But D_xx.cc tries to fill d2[...] which obviously can not work. What I did was insert if (n_spatial_dimensions == 3) ... and if (n_spatial_dimensions == 2) statements into the code.

Here's my updated version of the file:
