I got it working. I had the geometry error message and fixed it by re-adding the initial velocity while I had the bullet object selected making sure that the value `geometry` under `scope` showed '1 Body'. If this doesn't work for you make sure everything you inserted has the same geometry selected as in the video. I got the 'energy error too large' error also. This was fixed by setting the value `Reference Energy Cycle` to the same value as `End Time` under `Analysis Settings` to disable the energy error from being raised.
So how accurate is such a simulation? Looking at the energy the hourglassing is quite high? At least higher than what is suggestedo be in a save region.
In the video i focused to explain the procedure by taking a simple example. The accuracy can be increased by refining the mesh as it is very important factor determining the result.
+long cheng Default material are used in the tutorial i.e. structural steel. You can definitely assign any other material to bullet and slab from the engineering data sources.
Then probably there would be some error with your geometry,check the mesh settings .Applying the same method on the cad file used in this tutorial you can get the separate results easily.

I'm having this problem. "Solver error - energy error too large. Project>Model>Explicit Dynamics>Solution Tuesday, June 19, 2018 4:12:53 PM."
it is interesting video lecture. how can draw different angle by explicit dynamic with bullet penetration's and also how can gate residual velocity?
Did you find answer
Interesting video. Could you tell me why you deleted that contact condition ? Isn't it needed for the simulation to work properly ?

what is the material of the bullet ?The material properties are not given.

How to draw geometry. It's parameters
if i want's know the equivalent stress induced in each of the part i.e. bullt and plate separately, then how i can do this??
hello nikhil,
While inserting the equivalent stress option in the solution choose the desired part in the geometry .
HOW TO FIND PENETRATION PLEASE HELP VERY URGENT!!!
thank you.
I have already tried this but it showing geometry error while solving the solution.

Please help me find penetration all I can see is directional deformation but I need now kuch the bullet penetrates
sir can i ave cad file
check the description link.
thank u
Use free cad guys
... And you clearly do not know how to model an environment model using CFD, congrats!
