Future Work

Construct Manifold

Providing a user interface of modeling the way devices used to achieve the division of flows from a single source to many outlets.

The source is usually termed headers and the outlets are usually termed manifolds.

What is Manifold Flow Predictor?

Frontend Drupal run on Apache MySQL Linux

Backend Submitting jobs to HPC system

through the resource manager (Portable Batch System), which automates CPU and resource scheduling

Portal StructureLet multiple authenticated users

to use the super computing service atomically and securely without interfering others’ ongoing simulation process.

Let the customer retrieve their the information of their previous Manifold Flow projects according to their will.

ParaView is an open-source, multi-platform data analysis and visualization application

ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques. The data exploration can be done interactively in 3D or programmatically using ParaView's batch processing capabilities

userDifferent users should submit jobs as their IDs rather than as Apache user

Other featuresProduce graphs of residual values to allow users to determine whether

the model has sufficiently convergedAllow user to specify either pressure or velocity for boundary conditionsAuto-calculate number of simulation steps

Significance

The extrapolation of results from the laboratory to chemistry and industrial scale requires careful consideration of the design and process conditions.In order to do this, simulating the process in an accurate and visible way is very essential.This MFP provides a friendly user interface to do this simulation and return the simulative result when it is ready.
