problems in explicit dynamics simulation in ANSYS Workbench. PLEASE HELP !!!! 2

[german9011]

 I'm new with ansys if I can help it would be helpful.

the problem is that two solids are shocked, but one of them is going through the other, have already implemented several things different tutorials but the answer is the same. the only question when I change the location fixed support the results change. I've also tried putting speed and standard earth gravity but I do not lack anything the result.

This is the file

Hi,

I tried to look at your file - but you only attahced the .wbpj file, this is not readable standalone.
Please archive the file (using file->archive command in the workbench) and attach the .wbpz file, so it will be readable.

look assafwei this is the file thank you very much for helping

Hi,

Please take a look at the result scaling (left side of your image that yoo attached)
it is set to a very high scale, (10^8), change it to true scale and you will see there is no movement at all.
You didnt specify the correct BCs to allow movement of the box.

 

[assafwei]

I pressed submit too early...
the point is - there is no motion and no penetration. You need to add BCs (such as initial velocity) to the analysis.

 

[assafwei]

Again submitted too early...
I will also advise to get the two objects closer, they are about 50 milimeters apart, and the time the computer spends on just moving the box with no interaction is a waste...

 

[german9011]

thank you very much for the tips but since you added the initial velocity but the answer is the same.
the simulation is not generating results that WILL want.

 

[assafwei]

Ofcourse you dont see anything...
You put 200 mm/sec velocity.
The solution total time is 1e-5, this means the box is movit total 0.002mm...
Prescribe a mush bigger speed (lets say 900 m/sec -> 900000 mm/sec...) then you will see movement.
If you want to see collision - make the analysis time longer, or put the box closer in the start of the analysis.

look thanks if put shame on the speed in another unit but I think my problem was end time was very small.

thanks for your advice.
