Viewing OpenFOAM Results

In the previous section, we saved result file openfoam-example-results.tar.gz to an S3 bucket at destination s3://my-bucket/my-dir/openfoam-example-results.tar.gz.

One method to download the results file to your workstation and view it is to use the AWS CLI to interface with the S3 bucket where your results are stored. If you do not have the AWS CLI installed, please see the AWS CLI installation instructions for more information.

Using the AWS CLI command aws s3 cp, the result file can be downloaded to your workstation. The command below copies the result file at S3 URI s3://my-bucket/my-dir/openfoam-example-results.tar.gz to your working directory.

$ aws s3 cp s3://my-bucket/my-dir/openfoam-example-results.tar.gz .
download: s3://my-bucket/my-dir/openfoam-example-results.tar.gz to ./openfoam-example-results.tar.gz

You can decompress the results archive in your working directory using the following command:

$ tar -zxf ./motorbike-example-results.tar.gz

After decompressing the results tarball, will be contained in directory motorBike. To view the results, we can simply use the cat command to output the contents of the file to our terminal. The command below outputs the contents of file motorBike/log.decomposePar

$ $ cat log.decomposePar

Processor 0
    Number of cells = 640
    Number of faces shared with processor 1 = 64
    Number of processor patches = 1
    Number of processor faces = 64
    Number of boundary faces = 384

Processor 1
    Number of cells = 640
    Number of faces shared with processor 0 = 64
    Number of processor patches = 1
    Number of processor faces = 64
    Number of boundary faces = 384

Number of processor faces = 64
Max number of cells = 640 (0% above average 640)
Max number of processor patches = 1 (0% above average 1)
Max number of faces between processors = 64 (0% above average 64)

Time = 0

After decompressing the archive, you can post-process your results and create visualizations using open source software ParaView.
