• Multiple responsibilities from software design, testing, benchmarking, and support activities for solvers such as AcuSolve (FEM) and nanoFluidX (SPH).

• Development of multiphyscis solution support in Altair SimLab by coupling of various Altair’s native solvers such as Acusolve, EDEM, nFX, Optistruct and Flux.

• Involved in the design of Graphical User Interfaces to facilitate pre-processing, solution setup, and post-processing.

• Propose feature requests and create design specification documents.

• Use agile development tools to initiate, drive and monitor the progress of the feature support activities.

• Testing of solver and tool features supported in every software development cycle before release.

  • Carry out thorough internal testing of the support features.

  • Creation of regression test scripts to identify regressions in the future.

  • Create JIRA tickets for identified and reported issues and help in resolving them.

  • Act as a point of contact for technical details and consultation.

• Customer support activities.

  • Set up and run benchmark and Proof-of-Concept problems requested by customers.

    • For e.g. carried out a benchmark case study of mass-flow rate through an Automated Grill Shutter system in an automobile.

  • Create reports and presentations and communicate software capabilities, problem setup workflow, and benchmark results to customers.

    • For e.g. conducted weekly office hours meetings for customers and internal members on the existing feature and ongoing developmental activities on DOE, optimization, coupled-simulations, etc.

  • Provide training to prospects and customers in the form of technical discussion through Teams meetings, creation of tutorial videos, FAQ documents, and Industry-relevant simulation case studies.

    • For e.g. simulated and presented results in the Altair Global Technical Training seminar on Cabin thermal modeling.

  • Resolve queries, requests, and issues raised by customers through emails and act as a node of communication between the customers and developers.

    • For e.g. led the mesh file export support in OpenFoam format on customer request.

Project Officer,Centre for Industrial Consultancy and Sponsored Research, IIT Madras, India.

2017-2018

• Carried out the development of numerical algorithms and computational code for fluid-structure interaction under air-blast conditions.

• Developed novel modeling techniques for wall modeling, and accurate capture of jump discontinuities such as shock/blast waves and material interfaces (relevant for multiphase flows).

• Tested, debugged, and evaluated the model and solver performance by simulating validation problems on detonation of explosives, blast wave generation and propagation in air.

• Benchmarked the performance of the solver against Ansys (Autodyn), and OpenFOAM solvers.

• Designed and analysed novel approaches for blast wave mitigation.

• Published articles in reputed international journals and conferences.
