Adams Flex

[gwena]

Hello,
I'm using AdamsFlex. I meshed the flexible body with Ansys and imported the .mnf file in Adams flex.
The problem is that : The weight of the flexible body is 0.064kg in Ansys whereas its mass is 0.260Kg in Adams ! The correct mass is the first one.
Units are specified in SI (MKS)in both softwares and material properties too.

Someone have an idea ?
Thanks a lot !

looks like it's converted lbf to N ! bizarre. Try the ADAMS support people.

Cheers

I solved the problem

2 nodes with 'MASS 21' was created. This concentrated masses are constrained with a set of nodes at each extremities (CERIG option).
I set the real constants of the mass21 to 1E-7 in order to not disturbe the global mass. The bug was that I wrote 1E-1 in one of them.

Sorry....
