Errors

(OP)
Hello all

I am totally dispersed ,the time is running for my dissertation and i am stuck with thousand of errors
so please help me as much as possible,and i will be thankful for all of you

I have one bolt with complex geometry in concrete and steel connection(box) and i am applying tensile forces to this bolt also i defined pre load as well ,contact surfaces is an important part with simulation

To make thing easier i suppress everything and leave only the bolt with the preload and i got singularity problems and process terminate
i try run the model without the concrete and i got those errors in the monitor screen


Slave surface assembly__pickedset56_cns_ is a node-based surface used with surface to surface approach. In order to obtain improved stress accuracy with this approach, an element-based surface should be used instead.

For *tie pair (assembly__pickedset56_cns_-"assembly_cone inside"), not all the nodes that have been adjusted were printed. Specify *preprint,model=yes for complete printout.

For *tie pair (assembly__pickedset56_cns_-"assembly_cone inside"), adjusted nodes with very small adjustments were not printed. Specify *preprint,model=yes for complete printout.

THE RATIO OF THE MAXIMUM INCREMENTAL ADJUSTMENT TO THE AVERAGE CHARACTERISTIC LENGTH IS 3.34079E-02 AT NODE 554 INSTANCE CONE-1 ON THE SURFACE PAIR (General_Contact_Faces,General_Contact_Faces).

Not all the nodes that have been adjusted were printed. Specify *preprint,contact=yes for complete printout.

Slave node 1 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 4 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 5 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 6 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 30 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 31 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 32 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 33 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 34 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 35 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

Slave node 36 instance shank-1 will not be tied to the master surface "assembly_cone inside". The distance from the master surface is greater than the position tolerance value.

936 nodes are either missing intersection with their respective master surface or are outside the adjust zone. The nodes have been identified in node set WarnNodeMissMasterIntersect.

OVERCONSTRAINT CHECKS: THERE ARE 12227 BOUNDARY CONDITIONS SPECIFIED IN THIS MODEL. OVERCONSTRAINT CHECKS FOR BOUNDARY CONDITIONS SPECIFIED ON SLAVE NODES OF RIGID BODIES, OF *TIE OPTIONS, OR OF *COUPLING OPTIONS REQUIRE 5 Mb OF MEMORY. IF THIS IS A PROBLEM, PLEASE TURN OFF OVERCONSTRAINT CHECKS USING *CONSTRAINT CONTROLS, NO CHECKS or INCREASE THE MEMORY USED BY THE PRE-PROCESSOR.

Boundary conditions are specified on inactive dof of 36 nodes. The nodes have been identified in node set WarnNodeBCInactiveDof.

I really need help if anyone willing to help i can send the original file to him to have close lock and give me feedback on how i can eliminate the problem,

I really running out of time and i am really thankful for all of you

RE: Errors

(OP)
I am waiting for all you brothers to help me

thank you

RE: Errors

As I see, you have problems in the contacts between surface. Try to use the "Translate to" tool in Assembly part and put Clearance 0. So this way, you will be sure that the gap is 0.

RE: Errors

(OP)
Thank you very much
i have question to you, do i need to define contact if two parts have gap between them in reality
because this what i did,and maybe create the problem???????

please explain this to me

please
please

and thank you
