Main Output File |
|
The main output file generated by a Flexcom analysis (with the file extension OUT) contains an echo of all the specified input data. It is strongly recommended (particularly for an initial static analysis) that this file be used to check the accuracy of the input data, namely nodal co-ordinates, element connectivity, properties, loads, boundary conditions and time-step parameters. This should highlight any elementary errors in the input data specification before you embark on a series of dynamic analysis for a substantial load case matrix.
If an analysis fails to converge successfully, the program outputs the convergence ratio for each unsuccessful iteration – this is presented at the end of the input data echo section. There are typically 15 iterations (depending on the analysis type, and the time-stepping procedure if applicable), and the table will show whether or not the analysis was approaching the convergence tolerance. It will also allow you to identify the critical degrees of freedom. Refer to Convergence Ratios for further information.
It is also possible to augment the contents of the main output file with greater details in specific areas of interest. This affords greater transparency regarding some of the internal computations which are performed by Flexcom at run-time. For example, it is possible to request further information relating to...
•Instantaneous Convected Element Axes in the Finite Element Solution
•Solution Criteria Automation in Static Analysis
•Wave Spectrum Discretisation in Time Domain Analysis
•Internal Fluid Centrifugal Forces & Slug Flow
... any many more parameters besides.
