Time of ASE calculation

Hello,

I have a question regarding the speed of calculation. In attachments I am sending the screenshots from the calculation of nonlinear analysis of building. The workstation has 64 cores (AMD Threadripper 3995WX) they are all running during iteration process, but as you can see, the initialisation of the calculation took 1434 seconds.
This process as you can see on the image 1 below took 1434 sec.:

Then iteration started - image 2

And final calculation time was 1643 sec (image 3):

I would like to know that if it is also possible to speed up this initialisation process? On the workstation is 512 GB of DDR4 3200 MHZ RAM with ECC and 2 NVME SSD disc in RAID 0 configuration, with 13 GB/s read and 7,5 GB/s write speed. So if it is possible to utilize RAM or SSD disc speed?

Look into ctrl solv options (1-4), e.g. ctrl solv 4 which is a parallel solver

Thanks for the tip, but of course we use PARDISO solver and all cores according to task manager ale used, but only in the phase where iteration is running. Problem is the time until the first iteration is calculated.

I think you should simplify the model or make a coarser mesh. The model contains a lot of QUAD elements. More that 90 000 as far as I realized from the screen shot.
