Simulation plastics

Simulation Generality
1
Hello We are starting to use the plastics simulation in SolidWorks and I have some questions. We mainly work on rotating parts and so when we want a sufficiently fine mesh, we have calculation times of 8 to 8 hours. In order to reduce these times, we tried to make the calculation on a section of the part using the plane of symmetry. Except that it doesn't give the same result because, as its name suggests, it makes a symmetry with respect to the face, but it doesn't take into account the fact that the piece is circular. Is there a way to do it? The solid density as well as the shear modulus indicated at the material level, it must be measured at what (ambient?) temperature What influence does the shear modulus have if it is at 0?

Hello

I think this is the first time I've seen a question about Plastic Simulation (which is very different from Solidworks mechanical simulation.) and I'm afraid that the answers to your problem are rare because among the members few seem to be doing plastics processing

Therefore, I suggest the following:

If you start using the software, it means that you are under maintenance and that you have access to the hotline, they will be able to inform you.

Question: Have you had any training on this software?

Small remark: an 8-hour simulation is totally abnormal, it's a few minutes to 1 quarter of an hour maximum.

Good luck solving your problem. ;-)

Kind regards

Hello

I'm not simulating but for the question of temperature my logic would say in the expected conditions of use of the part. If it's indoors, yes a temperature of 20°C would be logical, otherwise if it's in a machine or outdoors you'll probably need a test at a minimum temperature and another at a maximum temperature. 

Otherwise, I can only advise you what Zozo, our mechanical simulation expert, says;)

HS on:

A little test on freecad simulation to see if it's feasible? ;) Who knows... maybe it works and for free

Hello. We use SWP regularly. From the moment you mesh finely (i.e. what you mean by "finely") it does indeed take hours of calculation if you are equipped with a "normal" workstation, dedicated to CAD, provided by an authorized SW reseller. If you want quick results, you need calculators, but then you have enough money I guess for much more powerful simulation software.

So making a simulation on a section is common sense, but the time can also be very long...
I think you have to optimize the calculation settings, use a machine that does just that and arm yourself with patience. Yours truly.
