How can a tapered spar cap be modeled in FEMAP 6.0

I want to use rod elements to model a tapered wing spar cap. There will be over 100 elements over the length or the spar cap. Writting a separate property for each element is very time consuming. I don't see a mesh command that will auto create the elements with varying cross-sectional area.

You could use the tapered beam property, but this is still cumbersome. I'm sure you're familiar with this capability, but let me know if you need additional information.

Thanks for your response. If I use a single tappered beam element to model a tappered wing spar cap, is there a way to use "mesh / refine" so that discrete properties are created by FEMAP for each new element or do I still have to write a separate property for each element?

This is still a problem. Another option is to create the geometry as a solid model, partition it off, and hex mesh it. This may make the model entirely too large though, so creating mid surfaces and using plates may make more sense.

Sorry I forgot about the difficulty in using Femap's tapered beam element. I ran into the same problem a while back and ended up creating multiple tapered beam properties.
