Computer specification is below.
CPU: Intel(R) Core(TM) i7-4930K CPU@3.40GHz 3.70GHz Memory: 64.0GB OS: Windows 7 64bit HDD: samsung SSD 128GB Hitachi 1TeraByte My problem size: Total number of Nodes 1,220,468 Total Number of Element 5,658,935 Total Number of Tetrahedrons 5,658,935 Total Number of Faces 1,441,722 Whenever I load above file, it takes 25 minutes, aproximately. Is there any method to load it faster? |

A mesh that size should take about 1 to 2 mins if not less. 25 mins is way too much. Can you try the same on another machine?

Thank you very much for your fast help. I will try to do that.

Hi,
That does seem far too long to load your mesh. I've loaded larger meshes on a much less powerful workstation in no more than a couple of minutes. Maybe contact ANSYS technical support. Good luck, Dave |

I would check your anti-virus is not being silly. Also SSD drives can be tricky to set up (I just spent this evening setting one up and it is now running 3 times faster than the default SSD setup) so some SSD optimisation can go a long way. Also - are you loading it from the local drive, or over a network?
The other comments are right - a 1.2 M node mesh is not big and should load quickly. So something is wrong with your system. |

I install ANSYS CFX to C drive(SSD) and my ANSYS files are D drive. Could it be a problem? I did not know how to optimise SSD but I will do it. Thank you very much all of you. I will write the solution note.

I optimized SSD but it reduced only 5 minutes. I moved my file to C, SSD drive but loading time took more time. I heard that geometry and mesh could take time a lot. My geometry has a lot of complicated internal shapes, i.e. boiler and tubes. Do you think is it possible? Another guy said to me that graphic card could cause this kind of problem. Graphic card is NVIDIA GeForce GTX660, 2GB memory. What kind of graphic card do you use or recommand to me?

If the internal shapes have thousands of boundary surfaces then that can slow things right down. A single boundary with a million faces loads quickly, a million boundaries each of one face will take forever to load.

Not that much...5 different tubes and 5 boundaries only. I am looking for solutions.

I am sure you are looking for solutions. Aren't we all?
As a test, how about you make a simple cube and mesh it with about the same number of nodes. Import that into CFX-Pre and then you will know whether your PC has a problem or if your simulation is what is slowing things down. |
