Post-processing with less timesteps than generated

Hypothetical situation: I ran a simulation with 1000 time steps and now want to do post-processing with only 250 timesteps. Instead of redoing a simulation with 250 times steps, could I simply import 1 out 4 VTU files in the sequence of the 1000 that were generated? Would this cause any issues? I te...

Re: .flow file units - inconsistent in cerebral repository models? (cc/sec?)

Hi Alain, You were correct in your interpretation of the 0052_H_CERE_H inflow data. I didn't read the referenced paper corrected, thought the data was some sort of average. I will contact the VMR guys and see if they understand what's going on. Thanks for pointing this out! Cheers, Dave Hi Alain, T...

Re: .flow file units - inconsistent in cerebral repository models? (cc/sec?)

Hi again David, I found another cerebral model within the newly uploaded repository models (amazing!), that is also a pulsating simulation very similar to my idealized model. Project: 0207_H_CERE_CA In this case, all the units/decimal points, boundary conditions and flow rates (graph below) matched ...

Re: .flow file units - inconsistent in cerebral repository models? (cc/sec?)

Hi Alain, The data in the flow file matches the assumptions made in the paper referenced for the 0052_H_CERE_H VMR entry. If your model/mesh does not have a length scale in CGS then you will need to use other units. Cheers, Dave Hi David, Thanks for getting back to me! Would it be possible to clari...

Re: .flow file units - inconsistent in cerebral repository models? (cc/sec?)

Would there be any technical reason to use another unit other than cc/sec for the .flow file?

.flow file units - inconsistent in cerebral repository models? (cc/sec?)

Hi Everyone! I've been running many simulations with SimVascular since the beginning of May to use it on my summer research project. I've now created an idealized MCA model with an aneurysm to study. As I've gone through the documentation over several weeks, I've understood that SimVascular does not...
