S-ALE Fails When Using MAT_ALE_INCOMPRESSIBLE
I am trying to do a simple bore in a box simulation where a dam of water is allowed to flow around in side a box, however, the simulation keeps failing with the following error:
*** Error 40660 (SOL+660)
The laplacian diagonal term for the element 1
is zero. It usually occurs when the nodes of this element
are constrained in all directions
The simulation makes just past the storage allocation lines then the error causes the simulation to fail before a run-time estimate is presented.
I am not exactly sure what this error means as even when I remove any constraints from the model I still get the same error. The .k file is attached but how I defined the materials is as follows:
*MAT_ALE_VACUUM - to model the air, section SOLID, ELFORM = 6
*MAT_ALE_INCOMPRESSIBLE - to model the water, section SOLID, ELFORM = 6
I filled the S-ALE mesh using the *INITIAL_VOLUME_FRACTION_GEOMETRY card.
Does anyone have any idea why this model fails to run?
