The overview of the new features are as follows.

Features for editing shapes

Now, imported shapes can be scaled, translated and rotated in "Import Shape".

• Scaling

  If "Scale" is selected as editing type, shape size can be changed from mm, cm, inch, feet etc... to m. And also any scaling factor can be set if you want.

  Scaling

• Translating

  If "Translate" is selected as editing type, shape's absolute coordination can be changed.

  Translating

• Rotating

  If "Rotate" is selected as editing type, shapes can be rotated with specified axis and angle.

Show/Hide a bounding box

You can toggle display/non-display of bounding box with icon at lower-right side of 3D view.

Displayed bounding box

Viewpoint fitting in 3D view

You can set viewpoint to show all shape in the 3D view rectagle with icon at lower-right side of 3D view. This feature is useful when you scale the size of shapes and lose sight of the shapes.

The overview of the new features are as follows.

New features in Calculation Settings

Following settings can be set in the Calculation Settings panel.

• Numerical schemes
• Matrix solvers
• Relaxation Factors

You can set "Normal", "Stability" or "Accuracy" as numerical schemes settings and "Stability" or "High speed" as matris solvers settings.

Calculation Settings

And you can set convergence criteria in a steady state analysis.

Calculation Settings - Steady state convergence criteria

The overview of the new features are as follows.

New features to output setting function

Some output-items are added to output settings panel.

Output settings - General tab

Following variables can be set as output on "General" tab.

• Residuals
• Courant number
• y+
• Vorticity
• Second invariant of velocity gradient tensol
• Minimum/Maximum values of variables for the calculation

Output settings - General tab

Output settings - Region tab

Following variables can be set to a region as output on "Region" tab.

• Flow rate (volumetric)
• Average/Integral values of variables for the calculation

Output settings - "Region" tab

Output settings - Sampling tab

Variable value at a specified coordinate can be set to output on "Sampling tab". The specified coordinate can be previeweded on 3D view.

Output settings - Sampling tab

Previewing a specified coordinate on 3D view

Show a monitoring window

If the OpenFOAM calculation is executed on a enviroment that has desktop system and gnuplot, an Allrun script starts a monitoring window when the OpenFOAM solver is started (this feature can be disabled).

Monitoring residuals

The overview of the new features are as follows.

Some features for base mesh settings

Now it is possible to easily set base mesh fineness with buttons. And the base mesh can be preview in 3D view.

Base mesh preview

Some features for mesh refinement

Now it is possible to set mesh refinement levels to a space that is specified with a cuboid or a cylinder. Mesh numbers between different refinement levels and refinement level for feature lines also can be set to.

Changing a solver for Boussinesq approximation analysis.

A solver for Boussinesq approximation analysis is changed from "buoyantBoussinesqPimpleFoam/buoyantBoussinesqSimpleFoam" to "buoyantPimpleFoam/buoyantSimpleFoam" because of the following reasons.

• Some heat boundary conditions cannot be used with buoyantBoussinesqPimpleFoam/buoyantBoussinesqSimpleFoam.
• buoyantBoussinesqPimpleFoam/buoyantBoussinesqSimpleFoam may be deprecated in the future (Ref. OpenFOAM Isuue tracker ID 2048).

By this change, it is now possible to use some thermal boundary conditions other than adiabatic condition and fixed temperature condition in the Boussinesq approximation.

Ver. 0.3 - January 8 2018

New features are added. The overview of the features are as follows.

Supporting Boussinesq approximation settings

Now it is possible to set Boussinesq approximation setting in thermofluid analysis. Select "Heat" and "Boussinesq approximation" on "Basic Settings".

Enable Boussinesq approximation

A feature to create cuboid and polygonal column as shape

Now it is possible to create cuboids and polygonal columns for defining calculation areas of external flow analysis. And, if the shapes to be analyzed are very simple, you can also use these functions to create the shapes without importing CAD data.

Outputing an Allclean script

An Allclean script to reset created mesh and calculated result will be outputed in exporting.

Ver. 0.2 - November 30 2017

New features are added. The overview of the features are as follows.

Adding shape file formats that can be imported

Example of importing Wavefront obj format file (The model is "Whale" CC-BY Miguelangelo Rosario)

In addition to the STL format, now it is possible to import Wavefront obj format (extension .obj) and Autodesk 3DS Max format (extension .3ds) files. This allows you to import shape data that is downloaded from Google Poly etc.

Supporting thermofluid analysis

Enable thermofluid analysis

It is possible to make data for thermofluid analysis. Thermofluid analysis feature will be enabled by check "Heat" in "Basic Settings" page.

Adding a physical property library feature

Physical Property Library dialog

Physical property library feature is added to "Physical Property" page. Physical property can be changed by clicking an icon next to "Property name" and selecting a property from the list.

Adding an initial condition setting feature

Initial Condition setting page

It is possible to set initial condition explicitly in "Initial Condition" page. If no condition is set to, a default value will be used.

Adding a parallel setting feature

Parallelism setting page

It is possible to set paralle number in "Calculation Settings" page. This value will be used in meshing and fluid calculation.

Ver. 0.1 - October 30 2017

We release a web-application for making analysis setting data for OpenFOAM. You can make settings with GUI and export the data as zipped directory.
