Hello, why do I get an error every second time, when running the following command:

./wabbit-post 2D --sparse-to-dense Ux_000000150000.h5 sparse_Ux.h5 4 4

This is the error which occures sometimes:

Operating system error: Nicht genügend Hauptspeicher verfügbar Reservierung würde Speichergrenze überschreiten

Error termination. Backtrace:

it is a known problem with no known solution. happens on other machines as well, even though more than enough memory is available.

I found the bug.

I am extremely curious :) it was driving me crazy and I spent quite some time on it :)

I forgot to add the allocation of the Runge Kutta tableau after having changed that in allocate grid... Seems like I forgot to set almost every possible parameter in sparse_to_dense... :(
