Hello - I am using the mnfres function in the flextk toolkit to pull the nodal displacements, velocities, and accelerations for a MNF after a simulation. So far, I've been able to get some good data from it but my team and I curious to know if we can…
Hello,
I'm creating a flexible suspension subsystem from a rigid subsystem. It involves replacing the control arms and the subframe with MNF files which has been carried out successfully. Next step is to adjust the subsystem to tune the wheelbase…
Hello!
I am just trying to add a flexible body with a force element between two of its interface nodes to reinforce the structure.
I can't share the model, but I think what gives a good picture of the idea is a flexible model of…
I am an Adam user with limited FEA background. I would like to know how I can properly create an MNF file using Nastran to represent linear flexibility in Adams.
Could I have a template with explanation on the important command lines in the Nastran…
Is it possible to perform Modal Stress Recovery in Adams? If so, is it possible to easily find the hot spots of the flexible body and to plot the time history of nodal stresses?
Hello,
I am trying to model a flexible body between two rigid bodies. I want the flexible body to be compressed or depressed based on the motion of the bottom and top rigid bodies.
In this picture, the blue and green parts are rigid…
I am trying to run a nonlinear model using Adams Max Flex. I am defining material properties with MATDIGI card. When I run the model, I get the following error message:
*** USER FATAL MESSAGE 7831 (SCA Service Loader)

Hello Adams Community,
I am using Adams MaxFlex to run a nonlinear simulation.
I am generating the bulk data file in my code and importing the resulting `BDF` file into my model.
My model runs perfectly fine when I use…
Dear community,
I have a multibody dynamics model of human body in Adams. Currently the intervertebral discs (IVD) are modeled as bushings with stiffness and damping. I am trying to model IVDs with flexible bodies option in Adams. I was able to import…
When I use Precision Move to rotate a body, the Orientation of the new part holds the rotation history. To be clear, when I rotate a body by 30 degrees about the Z axis, the new orientation looks like (0, 0, 30).
Is there a way to erase the position…
Hello,
The system i simulate is a propelled vehicule that is composed of two parts : first is a rigid part, the second is a flex part.
Until now, i started the simulations with a sim/statics command, in modal representation => the…
Hello,
I want to apply initial conditions to a model containing flexible bodies.
Doing this, I face the issue of massive deflections of the flexible bodies during initialisation.
My guess for explaination is:
It seems that the…
I am able to generate flexible bodies with NX Nastran however struggling with stress strain modes addition in flex body. I would be great if you can support on this.
Thank you.
Generation MNF files using Ansys works fine up to Ansys 18.2, but does not work since Ansys 19.0. See also KB8023510. Is there a workaround for fixing this issue? Thanks!
I am working on truck chassis+loadbody mnf in msc adams. Currently payload is attached to loadbody through RBE3 in NASTRAN directly. But as payload in truck changes I need new flex body every time.
my question is, can I retain payload connecting…
Hi All
I am running a nonlinear FE_PART model and would like to obtain the stress and strain values along the beam. Essentially I am just looking for the point of maximum stress. I am not sure if there is a post-process step I am missing,…
The stiffness field requires a real value to be entered and I am able to make it a function of time, but is it possible to make it as a function of another state variable?
Hi, Everyone.
I met a problem of outputting responses of a flexible body.
I just use a cantilever beam as a flexible body in ADAMS, and applying a moment load at one side, the 'total force on point' and 'total torque on point' output…
Hey all!
I'd like to enhance the investigation of the resonances of a mechanical system model incluing flexibles structures. Is it possible to extract operational deflection shapes from the System after the simulation using the Adams PPT? Or should…
