HI all,

When is it worth (and correct) to use mass lumping in simulations?
I have a 2D simulation with a resolution of 0.1 mm with a size of 100 mm, filled with triangles (using the opencarp Block function).

Kind regards,

For details you can refer for example to Pezzuto et al. 2016 or Pathmanthan et al. 2012

In general, the relative error will be bigger the higher the variability in terms of element size in your mesh. A quasi structured block mesh should be a rather benign case.
