How to Plot Vectors on a Plane?

Question

How to plot Vectors on a plain?

Solution

Vectors can be mapped on fluid domains (results, isosurfaces, isovolumes) or on cutting planes.

To start, create a cutting plane and assign Velocity (node) to the vector. As default, vectors are mapped in 3D form. Cutting planes are 2-dimensional. Vectors can be converted to 2D form also by selecting ‘Project vectors onto plane‘. Use slider or box to change the spacing between the vectors.

As a default, vector size represents the magnitude of the velocity. In the previous picture one can see that vectors are not obvious inside the room. Because vectors are small on the cells with lower velocity values. Under the Results tab, select VEC: Velocity (node). The Enable Clamping feature lets users limit the maximum and minimum lengths of vector sizes. Limit maximum length and set the overall vector size by relative scaling.

Next, Enable filtering and lower the max length. This will filter out the bigger vectors, thus remaining vectors will scaled up.

Finally, change the color mode of vectors by clicking the color icon:
