Error during the simulation

[Endel Ferraz da Rocha]

I am doing a simulation but isn't start, in anex the error.
Why if I change the "Number of Timesteps", 25680 to 1000, the simulation isn't start?

[David Parker]

I am not able to read the ERRO.txt file, just past the text here as code.

What platform are you running on? Which solver are you using? Are you running from the command line or from SV?

Cheers,
Dave

ERROR opening file [restart.0.1].

[Endel Ferraz da Rocha]

I am using the version by 2021 in the Windows 10, but the solver is the 2020, because I could find the new version in the site, only the SimVascular. So i made the donwload in the site this model, the number os steps is so expensive to use in the forst moment now, So i proporsed to put only 1000 steps, But the simulation doesn't start.

[David Parker]

There is no svSolver 2020 version so I assume you are using the 2019-05-28 version.

The error ERROR opening file [restart.0.1]. means that the solver can't find the file restart.0.1.

The directory you are running your simulation from should contain files like this (the .svpre file will have a different name)

Code: Select all

bct.dat		geombc.dat.1	mesh-complete/	restart.0.1	steady.svpre
bct.vtp		inflow.flow	numstart.dat	solver.inp

After changing any simulation parameters you need to press the Create the Data Files for Simulation button to create new data files. It may be that the simulation files where not created. Select the Show Details button on the popup displayed after pressing the Create the Data Files for Simulation button.

Cheers,
Dave

[Endel Ferraz da Rocha]

ok, It really is not creating this file, so, What do i to do it create this file?

[David Parker]

You need to look at the messages printed in the Details panel to see what the problem is.

Dave
