Hi,

I have generate a railway FE - modell (Rail, Sleeper...)  and want to use it as linear Flextrack model.  The Model is first imported as linear flexible model, it shows the right Modes and all recovered points. But when it is changed to the typ linear Flextrack, it shows no Modes and in Nodes set, there shows:

 "node xxx do not provide recovery information.Therefore, these nodes and all referencing faces are skipped.This may result in holes in the surface. Please check your results carefully or chooseonly nodes with recovery information."

I used Abaqus to generate .fbi. basis of a orphan Mesh. I hope to find out what the necessary conditions are for generating a linear Flextrack model and why such a phenomenon exists.
