Upload a Mesh
=============
Navigate to the **Volume Mesh** tab and select **Upload** to provide a mesh for simulation. Mesh configuration details are entered in the prompt.

#.  Select **Upload** and navigate to the `wing_tetra.1.lb8.ugrid <https://simcloud-public-1.s3.amazonaws.com/om6/wing_tetra.1.lb8.ugrid>`_ file.
#.  Select **Submit** to upload

Submit a Case
=============
Below the **Actions** heading select **New Case** to provide simulation configuration details. Flow360 provides a step-by-step guide for solver settings. Within the following pages, enter the corresponding values provided and select **Next** to proceed.

#.  **Geometry**

    "Mesh Unit" select **m**

    "Reference area" enter :inline-code:`1.15315`

    "Moment Length" enter :code:`[` :inline-code:`1.47602` :code:`,` :inline-code:`0.801672` :code:`,` :inline-code:`1.47602` :code:`]`

#.  **Freestream**

    "Freestream velocity" enter :inline-code:`286`

    "Angle of Attack, alpha" enter :inline-code:`3.06`

#.  **Boundaries**

    #.  "Boundary Condition type" select **NoSlipWall**
    #.  "Boundary Condition type" select **SlipWall**

#.  Continue selecting **NEXT** to proceed with defaults for the remaining pages. Enter text in the "Case Name" field at lower left and click **Submit** to start the simulation.

Review Results
==============
From the **Case** tab select the case link under the **Name** heading to review simulation results. The following tabs present real-time data from the simulation.

#.  **Description**: case submission details
#.  **Convergence**: plots of nonlinear residuals, CFL ramping, and linear residuals
#.  **MinMax**: plots and tables of flow field variable extrema, for debugging
#.  **Forces**: plots and tables of integrated loads, totals and individual surfaces
#.  **Visualization**: interactive mesh, contours, and isosurface display
