abaqus错误提示信息（ABAQUS error message）

Q: an error occurred while I was running abaqus:

ABAQUS error:the executable

C:

Aborted with system error "deny access" (error code 5)

Answer:

First look at the DAT and MSG files, there is no warning or error,

if not, there are three common reasons:

The parameter pre_memory in abaqus_ is too large

- a problem in the user subroutine. Check whether the correct

parameters are used when calling the user subroutine in the INP

file. You can try to debug a user subroutine with a simple

example to ensure its correctness. In addition, when writing

user subroutines, we should pay attention to set up some error

prompts as much as possible.

- ABAQUS's own bug. You can try to get rid of unnecessary special

settings in the model, and try to use the default values of

ABAQUS as much as possible. If the initial model has no problem,

and after modifying some parameters, the above error

information can be tried to restore these parameters one by one

to the initial state.

Is the software not working out?

If you take a few steps, look at files, search

for error, and see what the specific problem is

The grammar seems right

In general, the tie binding constraint: the action is to bind

the two parts of the model together, and there is no relative

movement between the two, which is equivalent to welding

together. If A and B are A binding, and B with node degree of

freedom always exactly the same, this is the same effect with

the coupling of ANSYS, ABAQUS in the surface and face binding

is the degree of freedom coupling surface corresponding to the

node. The definition of Tie master and slave surfaces is similar

to that of contact. When the stiffness, size and roughness are

contradictory, the size and roughness are dominant

However, contact requires add and remove operations, and tie

does not require such operations. It only needs to be defined

before the analysis step is started, and no action is performed

in the analysis step.

If the zero pivot appears in the MSG file, it shows that the

InP has defined the over constraint condition, and ABAQUS

cannot solve the over constrained problem automatically. For

example, in some part, the tie is defined, and the contact is

defined. The solution is to set the type to node region when

choosing the slave surface of tie or contact, and then do not

include the adjacent public nodes when choosing the region.
