Just installed 2015. Opened an existing file and continued to work on a project. When I tried to re-mesh a dual domain model into 3d I got an error saying that there were surface errors and the mesh failed. Mesh diagnostics show no errors. Mesh repair wizard finds no issues. This is a model that has already been repaired/optimized and ran various simulations.
I opened the same dual domain file in 2014 and re-meshed to 3D. No errors, no problem?
Got the same bug...just remove your injection cone for 3d meshing and it would work.
With injection cone, it won`t mesh BUT if you change to legacy mode, Log shows you (everytime you start meshing, 3 new nodes that have errors).
I passed some of those errors by sending all elements onto a new layer...tried it here..no chance..but deleting the cone was it.
Thanks for the help. Deleted the injection cone and it worked no problem. I wonder what happens if there is a feed system.
Mold flow is asking me to send my dual domain model but I think this is a bug like you said. I know its not the model besause I tried it on a few different models with the same result.
I am going to test it with a runner in place and see what happens. Where do you find legacy mode?
I'm happy that I could help you with that - worked as a beta tester part time during university and I think it wasn't that bad afterwards.
[But I am NOT working for Autodesk - now I wait for an service pack from the engineer answered above]
Still owe you an answer: Legacy (I only use it to find mesh defects that can't be seen in statistics when meshing fails because its an old fashioned way ]
3D Mesh - generate mesh - 2nd tap "Tetra" - 3D mesher (dropdown menue) - Standard "Advancing front" but changeable to "Legacy".
Hope that helps, too.
Dear Xu (hope that was the right first name),
Why can't I see your message in here???
Would you be able to reproduce the problem with a simple Dual Domain mesh?
If yes, would helpful if you could send me the input file.
It will be fixed as a service pack if it happens. However, the first thing is I need to reproduce the problem.
I have tried to generate a 3D mesh from a Dual Domain mesh with injection cones, but it did not fail.
On the other hand, if the problem is related to injection cones, you can tune off a checkbox "Apply extra refinement near gates"
When you see error messages by Legacy mesher, what did it say?
Now everyone can read.
I have my super special Moldflow destroyer file testet on this issue AND same bug - a simple roman number one, the same I send Autodesk for years because MF is not capable to show sink marks here. On a capital T it shows.
To your questions: Extra refinement is OFF - just meshing with those parameters: Global edge...2mm / Merge tol 0,1 / Match mesh checked / refinement unchecked - Advancing front 6mm and 1.2mm automatic opt. - both surface checked, without biasing, smooth all nodes. (Quite a standard setting)
Legacy mesher tells me 3 nodes are not connected...I selected them, corrected them (can't see any defects), re-started meshing...same Error with 3 different nodes...played that game 5 times.
Please tell me your results on my file!
Do you just want the study file. If so I can send to you. I have tried with multiple models with the same result. Turning off the injection cone eliminates the problem. I also removed the injection cone and replaced it with a simple cold gate. The problem came back. It will not let me change from a DD mesh to 3D mesh with any type of injection cone OR feed system in place.
Please let me know and I can send you ant files you require.

Thanks for the file.
I have tested on 3 machines but still could not reproduce the problem.
Could you please give me more details:
Your installed version?
Your Operating System?
Would be helpful if you can send me the mesh log. Just copy and paste from log window.
