For a domain (e.g 5Mx5M), Plaxis mesh generator can create upto 39244 triangular elements if the relative element size (re) is set to 0.335 and polygon coarseness factor is set to 0.08). Is there any upper limit on the number of elements in Plaxis?
Response by Plaxis support for Plaxis 2D 2017:
We can go up to about 22,000 15-noded elements. This has to do with the way we store and index the matrix. When the number of items in the stiffness matrix exceed the maximum of signed 32int (see also https://en.wikipedia.org/wiki/2,147,483,647#In_computing) then the calculation goes wrong. When adding structural elements or free field elements or other elements than of course this will add to the number of elements in the stiffness matrix. So this guidance for 22,000 15-noded elements is an estimated number and depends on the items used in the model.
hi..i don't think there is any upper limit but it depends on solution accuracy, your numerical model (your design requirements), degree of freedom and nature of loading. I too agree with the points mentioned by Mr.Mustafa that the number of items in the stiffness matrix exceed the maximum of signed 32int (see also https://en.wikipedia.org/wiki/2,147,483,647#In_computing) then the calculation goes wrong. I also recommend you to read PLAXIS tutorial and scientific manual for more understanding on this aspects..ok all the best..
I don't think that there is an upper limit, however, your pc specifications may limit the max. elements number
Hi, The number of elements for Plaxis 2d depends on the performance of your pc and sometimes on the license of your numeric code if it has expired certainly the number of elements will be reduced
