| 100 | * at the nodes (could be different from the vertices). This will be used for visualization purposes.
|

|

| 103 | 1. on a Beam element, Vx, at step 1, time .5, element id 1, interpolation type P0 (constant), vertices ids 1 and 2, one constant value 4.5

| 105 | 2. on a Tria element, Vz, at step 2, time .8, element id 2, interpolation type P1 (linear), vertices ids 1 3 and 4, with values at 3 nodes 4.5, 3.2, 2.5

---|
| 110 | * and the maximum number of nodal values, as well as the number of rows. Once we have that,
