mold feeding channels

[lzzmnl]

Good morning to all, I am emanuele of felt. I am currently a working student and I am faced with a problem regarding the filling simulation of a thermoplastic polymer mold. in pennies, a mold was designed and subsequently made and tested. here begins the problem: the test has not gone to good end since the product has remarkable aesthetic defects, so a hypothetical solution would be to add an injection channel. having the mold model already made to the cad is simple and fast to add a symmetrical channel. Before starting the change, I would like to perform a filling simulation with Moldovaflow to try to understand whether it makes sense or not to make this change. my experience with the software is not so much so I arise a question: having the power channels already shaped in cad (submarine injection) I can import them together with the model and then run the mesh of the whole object (especially printed multiple channels) or should I import only the model and build the channels with the appropriate commands? I noticed that mesh does it with triangular elements while channels with beams. Is there an explanation to this fact or is it just a speech about the heaviness of simulation?

If someone kindly knows how to give me an explanation, I would be very grateful..... I thank everyone in advance!

Hi.
usually before physically making the mold was made simulation
choosing the ideal point to feed it.
The injection point is wrong.
do not tell the size of the piece, the thickness, any sucking and zones of air trap
so your request is very generic
missing all the information, I should see the 3d model to respond correctly
change a channel or add other ones, create mesh and recalculate is not that problem

certainly, just use edesign of Moldovaex3d www.moldex3d.com.
What cad are you wearing or used?
...I'm sure that first you should do a minimum of analysis and simulation and then go on a prototype mold, anyway what made head to...
