Convert .bi4 into .stl?

Falko

Hello,

I want to simulate a scouring process via multiphase. The max. possible time and water volume dont suffice to represent the task properly. So I want to start a new simulation, but with the position of the sediment particles from the one before. Thus, modelling a constetutive scouring process using multiple simulation runs.
I thought that might be possible by implementing the last .bi4-file into the next simulation (maybe as a .stl-file). Is that possible and if yes, could someone give me advice on how to do that?
Thank you very much in advance!!

Kind regards
Falko

STL is only a format to define 3D geometries... so no information about velocity, density, or other SPH variables can be stored there...

Ok, thanks. Is it possible to do what I described on some other way?

If you want to restart a simulation, please read: http://dual.sphysics.org/index.php/faq/#Q_31

I conducted a restart computation in combination with the liquid-sediment-code.

I get the error message:
*** Exception (JCfgRun::ErrorParm)
Text: Parameter "-partbeginn:100" unrecognised or invalid. (Level cfg:0, Parameter:5)

In the DualSPHysics3.4_LiquidSediment_Help.out file its written that the parameter -partbegin can be enabled in the batch script.

Is it generally possible to combine a restart simulation with the liquid-sediment-code?
Or might there be some wrong formulation in my batch script?

Thank you very much for your help in advance!

You should ask Dr Georgios Fourtakas since he is main developer of the liquid-sediment-code

Hello
I want to simulate "Sediment Transport in seebed with wave maker (or wave generator)". Is it possible I do it in multi-phase case?
how I make a piston wave in multi-phase? is it possible?
