Hi, I would like to visualize a network representing arteries and veines.
I have a network, composed in the ensight format of 'bar2'. Thus, segments connecting nodes two by two.
I also have an element field representing the diameter.

Can I scale the diameter of each segment by the field diameter?

I know it's possible to do a node representation with sphere scaled by a field, but I would like to do that with the cylinders representing the elements.

Thanks in advance

Vinch,

I don't think that there is a direct capability that you are looking for (that I know of).

There is a "displacement" capability in EnSight, to displace any node by some field variable (a vector). The icon is along the top of EnSight, and looks like a spring/damper icon. This will take the node location, and displace it by the field variable. This is not exactly what you want to do directly. However, if you had a vector representing the normal vector * diameter, you could displace the node by this vector.

If it were me, I'd try by creating a normal vector using the "Normal()" PreDefined calculator function. I'd then multiply this by your diameter field function... ensure that this is a nodal variable, and then look to use the Displacement capability.

The fact that you only have bar elements and you really want shell elements to define the surface at some diameter away from the bar elements... this may create a more fundamental problem that you will not be able to overcome.
