Hi, In our model we use only hexa elements with simple boundary conditions and applied force. Step is Linear Perturbation. As a result we receive very strange results in reaction force: RF.Magnitude RF.RF1 RF.RF2 RF.RF3...

Hi, how can read in results forces in slave nodes of e.g. coupling distributed constraint. In Nastran this variable is called MPC force. Regards, Greg

Thank You. I use Patran 2004 for preprocessing but I cannot find this constraint there - is it with different name? Available are: explicit, rigid fixed, rigid pinned, linear (surf-surf,surf-vol,vol-vol), quad. (surf-surf,surf-vol,vol-vol), slider 12, elbow 17, pin 9, tie 5, revolute, v local...

Hi, I would like to use in Abaqus similar element to RBE3 which allowes me to apply concentrated force over some area. What type of connector is best for that in Abaqus? Thanks, Greg

maybe someone knows answer....please

Hi I have created independent instanec of few parts and connect them together in CAE. When I want to remove duplicated nodes with Instance-Merge/Cut, program creates new part with orphan mesh and I have to assign sections again and also aftere deleting such a part there are missing some of the...

ok but on other three similar places everything is ok so why just one corner cause problems - how to solve it as I want coord to lie on center line of spring

Hello, I've just defined a CSYS type=Cylindrical, to apply a cylindrical spring properties to it. I'm receiving the error message :"a material point in element xx lies on the polar axis. The orientation cannot be defined.Use the option orientation,System=rectangular or move the polar axis away...

Hello, I want do define spring simulating antivibration mount with radial, axial, torsional and conical stiffness. I understand that I should make 4 elements with nodes in cylindrical coord. Radial, axial and torsional stiffnesis are easily applicable with r (x), teta (y) and z but how to apply...

Hi all, is there easy way to display created amplitude in CAE. I check it in Visualization after reading results but it is rather not a case. Regards, Greg

Hi, I would like to model bolt connection between two shell plates with zero distance between. For solid modelling I use bar element with RBE2 (6 dof). I made simple model and compare results for independent node (RBE2) connecting two holes and with short bar element - results are very similar...
