Known Issues:

1. In the CPAS backend, a line between two points is defined as the geodesic on a sphere; however, it is visualized as a straight line on the Mercator projection map. Users are encouraged to insert points that span less than ten degrees.

 

2. After signing in and using the CPAS web interface for a period of time, users can be automatically signed out. If this happens, please kindly sign in again. When editing mesh specifications, please save periodically to avoid losing your work.

 

Q&A:

Q: How do I test my newly generated mesh on the CPAS platform?

A: We are in the process of adding a Real Simulation functionality and will place a notification on the CPAS website when it is done.

 

Q: One or more Mesh Specifications previously created do not appear on the “My Specs” page. What can I do to see them?

A: The web interface shows the 20 most recently edited mesh specification. Please export unneeded mesh specifications and delete them on CPAS to make older mesh specifications appear.

 

Q: The mesh/preview does not appear as expected if “Set Orography” is selected. My regions have high latitude in the North or South.

A: The dataset for the topographic variance (i.e. varsso) cover within the latitudes between 60ºS and 60ºN. This may be enhanced in future CPAS versions.

 

Q: When editing my mesh specification, I would like to delete a small region that is totally covered by another region. However, I cannot select it after clicking the delete button.

A: Drag one vertex of the small region outside the largest covering region. Then the small region can be selected and deleted.

 

Q: What is Max Resolution Gradient (km/km)?

A: It is the steepest allowed rate of change of resolution with respect to distance, which acts as a limit for resolution transitions. This ensures that there are no abrupt change of mesh spacing. The default value 0.0833 = 1/12 km/km means that a maximum 1km-resolution change is allowed for every 12km distance.

 

Q: The map panel sometimes appears broken.

A: There may be file loading synchronization problem. Try refreshing the browser.

 

Q: I edited a mesh specification when not logged in. Can I save my mesh specification?

A: Please use the “Export” button beside the “Reset” button to save your mesh specification to a local file. Then, after you log in, you can use the “Import” button for a new mesh specification (in the block with “+” sign) to import the locally saved mesh specification back to your account.
