Apply Enforced Displacment

Recommended Posts

Hi there,

 

I'm new at Hypermesh and I was wondering how to apply an enforced displacement as BC?

I've created a load collecter for my "normal" constraints, and another one for my SPCD constraints, where I put dof3 on 25 for a displacement of 25mm. I've read, that I have to create another SPC with the same settings as the SPDC. But How do I merge the constraints for the SPC loadcase? And when I apply the SPCD constraints and the SPC constraints with the dof3 setting then following error appears:

 

  *** ERROR # 176 ***
  A dependent d.o.f. of rigid elements is constrained in an SPC set.

 

Can someone help me?

Hi Xone92,


 


Looks like you are applying an enforced motion on a dependent node of rigid element which is not allowed.


 


SPC should be applied on the same node as SPCD with same DoF checked as marked for SPCD.

I think already an example was shared with you. What problems are you facing?

 

Let us know about the problems and we will try our best to help you :)

When I want to import fem file into hypermesh, I am receiving this error:

 

The file specified is not a Hypermesh database

 

How can I import fem file into hypermesh?

I want to apply four displacement boundary condition to the attached model in hypermesh (I am working in Optistruct). Please, help me out or explain how I can achieve it:

x_disp = x displacement

y_disp = y displacement

x_coord = x coordinate

y_coord = y coordinate

1. (x_coord = 100, y_coord = 35), (x_disp = 2.754, y_disp = -2.345)

2. (x_coord = 100, y_coord = 40), (x_disp = -3.754, y_disp = -1.345)

3. (x_coord = 15.3, y_coord = 100), (x_disp = 1.34, y_disp = 2.345)

4. (x_coord = 15.3, y_coord = 13.4), (x_disp = 2.34, y_disp = 1.345)

Thank you.

Hi Samuel,

 

Some of the coordinates which you specified are no where near the structure. Please check

 

Anyways you can use specify enforced dispalcement using SPCDs. Please search for SPCD/enforced displacement on forum for related posts.

I still do not understand. Could you please help add enforced displacement (-0.167, 1.234) on the node at the upper right corner of the model. Alternatively, briefly explain how to locate the node and how to apply such enforced displacement

This is the new error when I attempted to use enforced displacement:

 

*** ERROR # 186 ***
 An SPCD component must be constrained by an SPC or SPC1 data.
      GRID ID = 33
    component = 3
  LOAD set ID = 7
   SPC set ID = 1
   subcase ID = 1
