Install OpenFOAM in Windows 10 and Mac OSX

 https://www.openfoam.com/download/openfoam-installation-on-windows-10

 

Be careful. There is another version from openform.org at 

https://openfoam.org/version/8/ 

I have installed the openform.com version, also for Mac OSX.

The link below shows the discssions on their differences.

One problem with Simflow iis that the free version restricts the mesh to just 200,000 so it cannot even run a simulation on a cube using the mesh setup used in the car tutorial, in a non-symmetrical way. Need to use symmetry to reduce the number of meshes.

Unfortunately, the symmetry halves the Coefficient of Drag values.

You can use the instructions in the above link but it does not tell you how to install Ubuntu in Windows 10.

You need to enable linux in Windows in the Windows Features setting first, before installing Ubuntu LTS from Windows Store. Use LTS because it is more reliable and will be automatically upgraded.

After installing Ubuntu, I just copy the commands in the tutorial to the Ubuntu terminal. Unfortunately, <ctrl> V does not work. Need to click on the orange button at the top left of the terminal and edit first to issue the paste command.

Make sure you replace the "user" to the correct username that you use to login to Windows.

sudo apt install bison flex m4  failed.
However the tutorial appeared to work but I cannot find the case file.
We can install bison and m4 by using the install command separately.
sudo apt install bison
sudo apt install m4
But flex failed.
I tried the update command first:
  
sudo apt-get update
and then redo the command:
sudo apt install m4
It worked. You test whether you have installed properly or not by typing their names.
bison
m4
flex
If the terminal requests for input, it means that the program is installed.
Exit the request for input by type <ctrl> c.
This tutorial did not work. It puts it into Windows  user directory, called tutorial.
After running the icoFoam, there is no output at all despite showing no error message.
The tutorial below does not work.  paraFoam is not installed and cannot be instaled.
External Windows ParaView cannot be used because there is no output mesh.

 You can try the video here but it is too long. It teaches you how to compile maybe.

 


Paraview will automatically search for mesh files despite opening an empty open.form file. Just wait for a while. Need to click the apply in the properties button.

By default, it will not display. Enable the display by clicking the eye icon next to the file name.
 
To search for Ubuntu files, search in Windows for \\wsl$ and then open it.

Hit enter to search or ESC to close A Short Guide To Metric Nuts and Bolts Answers to the most Frequently Asked Questions Standard and Fine Pitch Threads How to identify nut and bolt strength grades How nut and bolt strength grades compare Maximum Tightening Torques Why specified torque is sometimes lower than the maximum Spanner Sizes Versus Bolt / Nut thread size Allen Key size versus Bolt / Nut thread size Correct Drill size for Tapping Metric threads in holes Introduction: Metric Nuts and Bolts This short guide is intended to give a very basic introduction to ISO metric nuts and bolts. It is intended for those working in plant and machinery maintenance to give enough information on to ensure that correct replacement parts are identified and used. Few parts are as critical in the assembly of modern machinery as the nuts and bolts which hold it all together and, at first sight, it seems that all metric bolts are basically the same. In fact, of course, nothing could be further from th...

CAN Bus Wiring Diagram, a Basics Tutorial

Image
https://tekeye.uk/automotive/can-bus-cable-wiring Index ↓ About ↓ CAN Bus Wiring Diagram, a Basics Tutorial The CAN bus is a common digital data network used in automotive, industrial, medical and scientific systems. The CAN bus is used for routing sensor data between pieces of equipment. The main advantages are high resilience to noise, reliability, low cost, simple wiring and ease of use. The disadvantages are that the data packet lengths are small, transmission rates are low and the message transmission cycle time can vary. This article covers the basics of CAN bus wiring, showing a simple CAN bus wiring diagram and how to wire up a CAN bus cable. It covers wiring for the common DB9 plug and socket often used with CAN bus test equipment. The DB9 is also known as 9-pin D-sub, DE-9 (its correct name), DB-9, serial connector, RS232 connector or null modem connector. The CAN bus is used in nearly every form...

Best Free CFD Tutorial: FreeCAD Openfoam CFD Workbench

Image
I find watching this video boring but the links are userful and the linked tutorial very helpful. Better than reading the instructiions in the FreeCAD Addon installation comments for CFDof. http://www.opensim.co.za/training.html   The tutorial that is useful in doing CFD for car is the one below: https://github.com/opensimsa/opensim/raw/master/Documentation/CFD/UAV2/CFD%20Tutorial%204%20-%20External%20Aerodynamics%20of%20a%20UAV.pdf   WINDOWS: ● https://www.freecadweb.org/wiki/Download ● Install CfdOF from Tools | Addon manager ● Go to Edit | Preferences | CFD to check and install dependencies   Of special note: I install the older version of Paraview as shown in the FreeCAD preferences. I downloaded cfmesh and HiSA from sourceforge. No need to look for binaries. It appears as though the master file  zipped file can be installed by FreeCAD.   cfMesh downloaded to C:\Users\othma\AppData\Local\Temp\tmpwg568v1r.zip Installing cfMesh... Install completed Download...
