I have a usual vtk file with a mesh of triangles and a scalar velocity.I want to obtain this type of plots:something like an elevation, but in paraview I just had obtained plane plots likeHow can I obtain plots like the first one?I Edited my message with an example of my vtk file. Note that the points of the mesh are in the plane XY (for that reason its third coordinate is zero) and I want to plot the first and second component of the velocity and pressuse, each one like an elevation (as the first image).# vtk DataFile Version 2.0Stokes Solution 2DASCIIDATASET UNSTRUCTURED_GRIDPOINTS           13  DOUBLE0.000000000000000E+000   0.000000000000000E+000  0.000000000000000E+0001.00000000000000         0.000000000000000E+000  0.000000000000000E+0001.00000000000000         1.00000000000000        0.000000000000000E+0000.000000000000000E+000   1.00000000000000        0.000000000000000E+0000.500000000000000        0.500000000000000       0.000000000000000E+0000.000000000000000E+000   0.500000000000000       0.000000000000000E+0000.500000000000000        0.000000000000000E+000  0.000000000000000E+0001.00000000000000         0.500000000000000       0.000000000000000E+0000.500000000000000        1.00000000000000        0.000000000000000E+0000.250000000000000        0.250000000000000       0.000000000000000E+0000.250000000000000        0.750000000000000       0.000000000000000E+0000.750000000000000        0.250000000000000       0.000000000000000E+0000.750000000000000        0.750000000000000       0.000000000000000E+000CELLS           16          64   3       7      12       4   3       5       9       4   3      10       8       3   3      10       3       5   3       4       9       6   3       6      11       4   3       4      11       7   3       4      12       8   3       0       6       9   3       5       0       9   3       4       8      10   3       5       4      10   3       1       7      11   3       6       1      11   3       2       8      12   3       7       2      12 CELL_TYPES           16       5       5       5       5       5       5       5       5       5       5       5       5       5       5       5       5POINT_DATA           13SCALARS presion doubleLOOKUP_TABLE default-4.59703889304213      3.82888363610970      3.81756522383386     -4.60835730531561      0.197145644934616     -4.59535605348466      0.195500198716605      3.82752829972580      0.187138058219474     -2.12293352900423     -2.12078991814064      2.21724715421349      2.21939076507648     VECTORS velocidad double0.000000000000000E+000   0.000000000000000E+000  0.000000000000000E+0008.41470984807897         0.000000000000000E+000  0.000000000000000E+0004.54648713412841        -4.54648713412841        0.000000000000000E+0000.000000000000000E+000  -8.41470984807897        0.000000000000000E+0004.20725870743923        -4.20725889966961        0.000000000000000E+0000.000000000000000E+000  -4.79425538604203        0.000000000000000E+0004.79425538604203         0.000000000000000E+000  0.000000000000000E+0007.38460262604129        -2.59034723999926        0.000000000000000E+0002.59034723999926        -7.38460262604129        0.000000000000000E+0002.39717406023838        -2.39717405652409        0.000000000000000E+0001.81026401191967        -6.60460085064085        0.000000000000000E+0006.60460083608821        -1.81026405008086        0.000000000000000E+0004.98756220389105        -4.98756217656822        0.000000000000000E+000
Elevation plot of a 2D plot - paraview vtk

A good way to achieve this is to use the Warp By Vector filter to warp your field in the Z direction using the value of your scalar.Just to give a brief overview,The warp by vector warps your field in a direction using a vector. If you wish to warp your field in the Z direction perpendicular to your XY plane, then you need to create a warp vector in the Z direction. This is very easy to achieve using the calculator and the kHat vector.Then you can rescale the value of the vector to obtain a warping that is pleasant to the eye.This is the easiest way to achieve this type of graph using your (X Y 0) type of vtk files as far as I know.
