Getting CMC running

[JJEldridge]

Hi,

I'm trying to get CMC-COSMIC running in a virtualbox linux machine, everything installed and setup correctly but when I come to run CMC I get a seg fault and nothing evolves. I'm using the plumber sphere example. I'm guessing I've not got enough memory allocated to the machine. What are the memory requirements as I can't see that anywhere?

If the required memory is less than 12Gb what else could the issue be?

Output from command line copied below. Thanks!

Jan.

Hi Jan,

From this it's not obvious what could be going wrong, since the parameters all seem reasonable and consistent with the Plummer sphere example. Can you post the command line call you're using to run CMC?

Thanks,
Carl
