specifiying an exporter with -e causes an error - if no exporter is needed.

Running pure post-processing example should not crash, if an exporter was specified with the -e parameter.

This would allow easier automatic testing.

The BaseExporter aka -e base should be your friend if you want a dummy exporter.

ps. If there is no exporter execution, then there is no the simulation output in the memory. Hence the post-processing fails.

[markus-stoll]

Yeah but how to decide if to use -e base or -e sofa when you run several MSML files for testing?

The simulation output is not needed in memory - the post processing is only using file data.

[markus-stoll]

sorry for opening/closing... What we could need here is a check, if the simulation run is really needed before trying to start the simulation with an empty description.

[wadoon]

Then this not post processing (in the sense, it is executed after the exporter)

[markus-stoll]

yes but in the sense of processing already existing simulation results. The same problem occurs if you only have preprocessing operators.

I think the using the -e exporter parameter should not enforce that a msml simulation has a scene included.

[markus-stoll]

exporter should also work without a defined scene.
A warning should be displayed.
