Problem solved!

It seems that when I change the grid resolution in the Sofa Modeler, it keeps the edges, quads and hexaedra from the previous resolution so, if I set them to 0, it automatically set the adequate amount of edges, quads and hexaedra.

Lot of thanks!

Thanks Hugo,

but now I have problems with the grid resolutions. If I change to n = “3 3 3” for example, with the SparseGrid I get a cube formed by 2x2x2 sub-cubes; but with the RegularGrid I get an error and the simulation doesn’t work.

The idea of the simulation I’m trying to do is to fix the vertices when y = 0 (simulating the floor) but with different “structures” (I mean, different subdivisions) of the cube.

Sorry for the inconveniences.

Thanks,
Cristóbal

Yes, tell me if you need more:

<SparseGridTopology name="sparseGridTopology3"  fileTopology="mesh/cube.obj"  n="2 2 2" />
<MechanicalObject template="Vec3d" name="mObject1"  position="0 0 0"  velocity="0 0 0"  force="0 0 0"  externalForce="0 0 0"  restScale="1"  showObject="0"  showObjectScale="1"  showIndices="0"  showIndicesScale="0.002" />
<FixedConstraint template="Vec3d" name="fixedConstraint3"  indices="0 1 4 5" />
<WriteState name="writeState1"  listening="1"  filename="FinalPos_SOFA" />

Thanks for the quick reply!

Cheers,

Dear Hugo,

yes, all clear! After some tests I decided to keep using UniformMass, but specifying the TotalMass instead of the Mass.

Even though, all the information has been useful.

Thank you!

Cristóbal
