Opens a file and closes the actual file if necessary.

In the different modes you can open the following file types:

  • Geometry Mode: *.pcs: Containing geometry data only.

  • Materials Mode: *.mat: Containing material data only.

  • Simulation Mode: *.crys ; or *.crys.gz: A *.crys file or a compressed *.crys.gz file contains all data available for a simulation model, including geometry and materials data.

    You can open a *.crys file by loading the Entire file or Without View factors.

This item is not available during the computation.


Saves data into the opened file, or opens the Save as... dialog. If no file is defined, see Save as ....

Closes the opened file.

Read/Save viewfactors

Crysmas saves only Gebhardt factors in the crys-file, not viewfactors. When emissivities change, either by changing them in the materials dialog, or because they are specified as temperature dependent, the viewfactors are needed to recompute the Gebhardt factors, and recomputation of viewfactors can be time consuming. Therefore the possibility is given here to save viewfactors to a separate file, which you can do e.g. directly after first computation of viewfactors. If you then load the viewfactors again directly after loading a crys-file it will not be necessary to recompute viewfactors when emissivities change. Do not load viewfactors from file if your mesh has changed!

Import File

Opens the Import File dialog for importing a *.dxf file with geometric data of the furnace, see Importing a CAD File (dxf-Format) and Import File.

This item is only available in Geometry Mode.

Interpolate crys

Overwrites the values of all variables in the actual *.crys file with the variables already calculated from another *.crys file.

This function is useful when you make more calculations on the same geometry and the geometry with a refined mesh.

This item is only available in Simulation Mode.

Interpolate raster

Transfer tabulated data into the CrysMAS model.

first row of the table file the pair of parameters M,N should be entered. The file should contain N columns and M rows. In the

In the second line 4 numbers: r_min, z_min, r_len and z_len should be entered. r_min and z_min mean the radial and axial coordinates of the origin of the raster, or its lower left corner. The parameters r_len and z_len mean the radial and axial extension of the raster.

Then follow M rows with data.

Each row contains N entries of the field data. The radial and axial distance between neighboring points in the raster can be computed as r_len/(N-2) and z_len/(M-2).

An arbitrary field value can be contained in the table. The value will be interpolated into the numerical field selected in the main CrysMAS window via the actual variable.

Additionally regions where the data will be interpolated should be selected. The data will be interpolaated only into selected regions. No interpolation will be done outside of the selected regions.

Both, interpolation on the structured and on the unstructured mesh are supported.

A short memo of the data format is written also on the top of the dialog window.


Opens the dialog for joining cartridge and furnace, see Join.

File Info

Provides information about the actual *.crys file, see File Info.

This item is only available in Simulation Mode.


Opens the Print dialog which depends on the installed printer. You can print the image visible in the window into a file or directly on the printer.


Opens the dialog for saving the visible image into a picture file, see Screenshots.


Opens the Preferences dialog, see Preferences.


Closes the file and exits the program.
