I would like to have time dependent material properties in MES (nonlinear analysis). The input would be similar to temperature dependent properties, but replacing the Temperature column with Time.   A good example of where this would be used is to simulate the curing of concrete. Before it sets, the modulus of elasticity is low. Once it sets, the modulus is high. Temperature dependent properties do not work because there are steps where the model has the same temperature but different material properties.   Another use would be to "remove" parts from the analysis. Material properties cannot change in a restart analysis, so you cannot stop an analysis, suppress a part (or change its properties to "0") and restart. But with time dependent properties, you could essentially remove the effect of parts from the analysis. (There would be limitations since the parts would still be in the model but weak, and distortion may be a problem. But it could solve some problems that are not possible currently.)   Show More

Hi   When copying a scenario it should very valuable (and normal!) to have a full clone of the scenario we copy actually when copying one with an MES analysis and several surface contact and groups involved, on the copy we lose all those last definitions...very damageable for complex models when we want to changing the mesh   thanks Show More

On opening a file, I'd like to be able to choose which Design Scenario of that file to open to.  Kind of like the File/Open options in Solidworks which allow you to choose model configuration on open.  This could speed workflow and give us a means of avoiding a problematic DS on open.   I know a similar suggestion has been made in the past but I think the solution could be simpler than what was suggested earlier.  I also think that suggestion may have been miscategorized and may be overlooked or misunderstood.

If it could be easy to make a restart analysis as it is in CFD...   And it could also avoid to lose the results when running very long simulations with MES and getting, after few hours, a  Error 0 reading file error...     Show More

Hi     When you post process a value and want to change the min and max plotted value, you can do that. The thing is that when you define one for, let's say a stress result, using this setting with another one (let's say displacement) is senseless     So, it could be interesting to be able to lock the user limit for a kind of result to avoid such thing.     Alain Show More

Hi     When using a non linear curve (elasto plastic), it should be very interesting to be able to plot the defined curve Show More

I would love to have Electromagnetic capabilites in Simulation Mechancial.  We use both permanent magnets and electromagnets in our designs.  A good tool that would simulate both static and dynamic situations in 3D would be wonderful.   A simple example:  Permanent magnets are to be used to mount breakaway tooling in a machine.  How large and powerful are the magnets required to be? How far apart should they be?  What does the force to distance curve look like as the part is knocked off?   Electomagnetic design would also allow for design of motors and solenoids.   I seems that should not be too much of leap from the electrostatics available and a whole lot more useful.

It would be great is Nastran could support the patterning of connectors.   Use case example: When testing a bolted pully/cog and hub assembly each bolt connector must be added in manually. If the part in question had a substantial number of bolts (i.e. a huge ring gear on the base of an excavator) it would take way too long to individually add the connectors. The alternative of using the solids would be exceptionally taxing and lengthen the analysis time by a huge factor. Show More

We would like to be able to fully integrate Creo3 ;actually only Creo2 is supported ;    but creo3 is supported by CFD software.   Show More

Hi   We would like to have a full associativity with Simstudio in the sense that all the BC, material and loads are conserved when going a second time to Sim Mech   Actually it is only running perfectly with MoldFlow   Thanks Show More

It would be extremely useful to be able to select the nodes belonging to a non-planar surface (a tube, for instance) and apply a pressure normal to that surface without having to define a new normal point at the center of each tube. Many other FEM softwares do that already. Show More

I would appreciate it if some time went into improving cpu usage with the SOLIDX.exe solid meshing engine. I have a 10core 3.1Ghz processor that is not utilized at all by the SOLIDX.exe engine. It uses approximately 5% of my cpu and only runs the cpu at 41% frequency.   Currently meshing takes me much longer than running an analysis. When an analysis runs my CPU is maxed out with all 10 cores running at 105% frequency.   I don't know how this cound be acomplished but it seems like there is a lot of room for improvement.

Hi   Actually the MF direct coupling works only with hybrid mesh   sometimes we have to go to a full tetra mesh..but it is not possible with the software...so it would be very useful     thanks Show More
