IMPORT MBF
CAEPIPE can import model data from a text file, which may be created using a text editor and should have the extension: .mbf (model batch file). This text file may also be created for an existing model using the Export command from the Layout window.
To import a model, select the menu command File > Import from the Main window.
The Import Model dialog is shown.
Select the model batch file (.mbf) and then click on the Import button. The batch file will be read and the corresponding model file (.mod) will be created and then shown in the Layout window which can be further modified or analyzed.
For detailed information on the .pnf and .cii file import capabilities please contact us at support@sstusa.com.
Command line operation
Dragging and dropping an .mbf file on CAEPIPE.exe will import, analyze and produce the results in .csv format and close the program. On the other hand, dragging and dropping the .mod file on CAEPIPE.exe will open the .mod file. Using the command line, you may have CAEPIPE analyze and produce a CSV results file thus:
C:\CAEPIPE> caepipe.exe sample.mbf (Enter)
The above command will produce a “sample.csv” file in the same folder as the .mbf file.
Format of .MBF
The input data is given in the following order. Except for the heading the start of each section is indicated by a keyword. The data for that section follow. Only the first three characters of the keyword are significant. See an example MBF at the end of this appendix.
Note:
CAEPIPE input for Concentrated Mass, Ball Joint, Rigid Element, Valve, Bellows, Slip Joint etc. require the “Weight” of that item to be input in lbf, kgf etc. and NOT its mass. So, whenever mass is required for a calculation as in the case of forming Mass matrix for dynamic analysis, or in calculating inertia force as (mass x acceleration) for static seismic analysis, CAEPIPE internally computes the mass for each item to be equal to (weight / g-value).
Similarly, for density of pipe, insulation and lining materials, CAEPIPE requires “Weight Density” to be input in lbf/in3, kgf/m3 etc. and NOT its mass density.
