Contact analysis: non convergent

Altair Forum User

Hi. I have been trying to perform a non-linear quasi-static analysis to simulate a contact but it doesn't by any means converge. I don't understant the reason. Could you help me? Thank you. This is the file: https://www.dropbox.com/s/asybtschpa1fpsk/compito_2_13.hm?dl=0

Hi Mirino,

please include the following PARAM card.

Control Cards>> PARAM>> EXPRTNL>>CNTSB and run the analysis.

Altair Forum User

Hi Prakash

thank you for answering. I have tried including that card but it still doesn't work.

Altair Forum User

Hi Mirino,

I shared the modified deck with you, please run the same at your end and check if you are through the error.

Altair Forum User

Thank you Prakash, I will try and let you know.

Altair Forum User

Hi Prakash, obviously the file you shared with me works. However, I tried activating the cards EXPERTNL and CNTNLSUB and I also tried setting in the NLPARM card NINC=25. However, It doesn't converge. What are the changes you made?

Mirino,

Can you remove CNTNLSUB and change the EXPERTNL to CNTSTB instead of YES?

Altair Forum User

Hi Prakash

I'm using Hypermesh 12.0. Inside Control cards-->PARAM I have between many options EXPERTNL and CNTNLSUB. Inside EXPERTNL, I can only choose between YES and NO. The same thing for CNTNLSUB. What am I going to do?

Mirino,

could you please let us know what are all updates you have?

You can find the software updates and graphics information from HyperMesh>> Help>> Updates and system information

http://forum.altairh...n-your-machine/

CNTNLSUB is for continuing non linear subcase from a preceeding NL subcase.

So, it is not necessary for you as you have only one subcase.

Can you try with EXPRTNL>> YES and without CNTNLSUB?

Altair Forum User

Hi Prakash, I have tried activating only EXPERTNL and not CNTNLSUB, but it still doesn't converge.

However, I have fixed the problem in another way. I opened the file.fem with an editor (Notepad) and I wrote in at the certain point this line:

$

PARAM,EXPERTNL,CNTSTB

$$

And actually it worked finally.

On the other hand, since I had the same problem (non-convergent analysis) with another model, I tried to insert again PARAM,EXPERTNL,CNTSTB. This time it didn't work: LOAD STEP 0.1, 0.2, 0.3 ..., 0.9 were convergent, while LOAD STEP 1.0 wasn't.

Mirino,

It can be seen from the out file that upto 90% load the model is stable but beyond 90% no convergence is seen.

So, please consider reducing the load.

Altair Forum User

Hello,

it looks like there is a io-problem. Take a look at the error 'Error opening the scratch file './supporto_09_1992_s44.rs~' ....

Please check if there is enough disc space and you have all access rights.

Regards,

Mario

Altair Forum User

Hi Mario,

Okay then the issue is with the disk space to write the scratch files.

Also, it looks like the run fails when 100% load is applied to the model due to the scratch file.

You may have to free up some memory to get the scratch files written or you can choose a different location to write the scratch files.Please refer to the OptiStruct Run Options (image below)

Hi. I reduced the force by 10% (from 24N to 21.6N) to match the LOAD STEP 0.9 which was convergent. With this new value of the force however, LOAD STEP 0.9 was convergent, while LAOD STEP 1 wasn't. Then, since the EXPERTNL was activated, the LOADSTEP 0.95 was calculated. The bottom line is:

LAOD STEP 0.9998 was convergent

LOAD STEP 1.0000 was NOT convergent.

(Now I no longer have the problem with the disk space since the error is merely: *** ERROR # 941 ***

Hi Mirino,

Okay, so the model is stable with 99.8% of the load and anything beyond it is not able to converge.

Altair Forum User

Hi Prakash. 99.98%. How is that possible and how can I fix this problem?

Altair Forum User

Hi,

it seems to be a contact problem.

As you can see, up to load 0.9 there is no contact. Then at 1.0 exactly half of the elements (230) are in contact. From this point the iteration has problems (since before there is nothing to iterate).

Hints:

please check all your contact parameters

be sure you know what all the parameters are doing

i prefer for a normal shell-shell open contact: TYPE=SLIDE, MORIENT=OPENGAP, SRCHDIS=1.5 x distance of contact opening (be sure to have different contacts for different distances) , ADJUST=NO, DISCRETE=S2S for HW13)

if you have only contact non-linearity (linear material and load), then change NLPARM to:

NINC=1, KSTEP=1, MAXITER=50

(try to lower the convergence criteria and take a look what happens)

Best regards,

Mario

Altair Forum User

Mario,

Yes, when the parts are in contact there could be stability issues which leads to a non convergent solution at the end.

Most of the users think that search distance is the distance between parts which have contacts but it is not. As you said one should have to learn what the parameters in the contact card actually mean.

Altair Forum User

Hi. I have been able to make the two analysis run. I used a property with card image PCONT and inside NLPARM I set the value as:

NINC=10

MAXITER=25

CONV=UPW

EPSU, EPSP, EPSW as default.

To make the analysis run I increased the magnitude of the force. As a result of this, in one of the analysis if the magnitude of the force is <54000N the analysis doesn't converge. If the magnitude is >54000N, the analysis converge.

Altair Forum User

Equally, if I want a force with an magnitude less than 55 000 N, setting NINC=1 as Mario suggested, the analysis converges.

Altair Forum User

Hi everibody!

I have the same problem with my simulation. When it starts last iterations i have problem on UPW and after many simulation i really don't know ho to fix it. We tryied first reducing the tollerance on EPSU EPSW and EPSW, then reducing Ksteps (from 5 to 1) and increasing NINC (from 10 to 20).

After some attempts i decide to reduce load (although is not properly correct for the fisic model that i'm trying to simulate) from 60000 to 10000.

EXPERTNL and CNTSTB are activate. What can i try to fix this issue?

Altair Forum User

HI @Lorenzo Loscalzo

Can you please share the entire .out file?

*** OptiStruct defaults set from:
install config file: C:\Program Files\Altair\2017\/hwsolvers/optistruct.cfg.

NOTE # 9199
MSGLMT=STRICT is active, all messages will be printed.
You can suppress some less important warning messages by use of
MSGLMT=BRIEF or UNREF (in config file or in the input data).

2 PARAM(s) were set:

*** WARNING # 4783
Finite sliding is ignored for contact because there is no large-displacement
analysis.

*** INFORMATION # 815
The total number of rigid elements, whose rotational dependent d.o.f.
are removed because there is no need to constrain those d.o.f., is 47.

*** INFORMATION # 3203
In order to produce more realistic results with nonlinear friction, gap offset
was automatically set to NO. This may cause failure of rigid body balance,
especially on models without SPC support. To activate gap offset,
set GAPOFFS to YES on the GAPPRM card.

*** INFORMATION # 3433
MUMPS solver is used by default for nonlinear analysis at subcase 3.

The amount of memory allocated for the run is 2461 MB.
This run will use in-core processing in the solver.
MUMPS solver will allocate memory separately and may
run in different core (in/out) mode.
