Brief description of the drawings
Fig. 1 is the flow chart of the calculating of structural strain energy entropy of the present invention characterization and result treatment system.
Embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Calculated the present invention provides a kind of structural strain energy entropy characterization and result treatment system, its basic thought are by rear
Platform calls finite element analysis software to be calculated, and by the secondary development function of finite element analysis software carry out result extraction and
To the reprocessing of result (such as text is shown, the form of 3D point cloud is shown)；It is soft finite element analysis need not to be opened in gui interface
Part, eliminates a large amount of occupancy of computer resource when GUI starts.No gui interface calls background analysis, result extraction ratio to have GUI circle
The mode speed in face is fast.
Fig. 1 is the flow chart of the calculating of structural strain energy entropy characterization and result treatment system.As shown in Figure 1, the flow includes：
Step 1：Initialization.
In this step, the operating path of system is set, required resource file is copied to spare under corresponding path.
If working directory is not present, working directory is created on hard disk；If catalogue has existed, corresponding resource text is only replicated
Part.
Step 2, model treatment.
In this step, to needing progress finite element analysis model file to handle, such as open, edit, preserve.Having
Before finite element analysis, manual edit, such as addition annotation, change point can be carried out to the model file (Inp files) for completing pre-treatment
Analyse the information such as result, analysis step, incremental step.It can modify as needed to model file in this step, pass through guarantor afterwards
Model file is automatically placed under working directory by the function of depositing file；It can not also edit, directly carry out preservation operation.
Step 3：Submit operation, monitoring.
In this step, create submission operation for the model file of back editor and terminate the autoexec of operation.
The system automatic identification computer CPU quantity, quantity workable for analysis is limited in below actual CPU quantity, and when calculating
Maintain the normal operation of computer.Operation can be submitted later by creating autoexec, and can monitor being currently running for task,
If not occurring surprisingly exiting, task run can normally carry out in next step；If there is miscue, need to return to previous step
Inp files are edited again, the submission, monitoring of this step are carried out again afterwards, until normal operation finishes backed off after random.Separately
Outside, the analysis being currently running can also be terminated by the order of termination analysis in this step.
Step 4：Extract result.
Analysis normal operation can carry out the result extraction of this step after finishing, start finite element using no gui interface
Analysis software and exectorial method opening result extraction module.System can be with after selection analysis destination file in this step
All analysis operating modes in automatic identification destination file, incremental step, unit/node collection；User can be joined as needed
Number is set, and extracts result afterwards.The system can realize analysis operating mode, incremental step, unit collection, set of node, result as needed
The multiple selection and repeatedly extraction of type.Unit result mainly includes stress data (principal stress, each component of stress), and strain energy is close
Spend (and calculating entropy evaluation result).
Node result mainly includes modal displacement, in order to carry out 3D display to displacement result, passes through when extracting modal displacement
The Program extraction initial coordinate of model file interior joint, and with the displacement data of each node destination file is write in the lump.This
System supports extension, and other results according to demand can be extended system.The result of extraction is write file to treat by system
Check or subsequent treatment.
Step 5：Check result.
The result extracted in a previous step has all been written into file, can open it in this step with the shape of text
Formula is shown.Stress, the analysis result that strain energy density is unit, can be by the system directly by list for stress data
Maximum stress in first numbering, the component of stress and structure of corresponding principal stress, all directions is shown in gui interface and supplies user
With reference to；For strain energy density, the system can be shown in a manner of element number, strain energy density, can also be to result
Data are reprocessed.In addition, the display to displacement data can use the form of text, such as according to node serial number, corresponding
X, Y, Z coordinate are shown, the node initial coordinate and modal displacement data that the system can also be obtained in read step 4 are calculated
Deformed node coordinate is obtained, three-dimensional visualization processing is carried out using the Mayavi storehouses in Python, according to node
Initial coordinate and deformed coordinate draw each node with different colors in three dimensions respectively.Show column joints deformation
Front/rear point cloud, can allow user more intuitively to check and deform front/rear shape etc., and user can pass through mouse pair
Point cloud such as is rotated, is amplified, being reduced at the deformation operated with observation structure everywhere.
So far, this flow terminates.
