Calculate the deflection of 3 different size acrylic panels

We seek a skilled engineer to calculate the deflection of three distinct acrylic panels. The panels include an 8mm circular panel with a diameter of 1580mm, a 10mm circular panel of the same diameter, and an 8mm rectangular panel measuring 3000mm by 1500mm. The circular panels are fixed around their perimeters, while the rectangular panel will be analyzed in two configurations: fixed around the perimeter and simply supported on all four edges. A comprehensive deflection report, including visual data representations, is required for all configurations.

STAR-CCM+ + TAITherm Cabin HVAC Thermal Comfort Debug/Fix

Automotive Cabin Heating Thermal Comfort Simulation Fix (STAR-CCM+ .sim + TAITherm Human Thermal / Berkeley Comfort) We are looking for an engineer who can run and troubleshoot an automotive cabin heating thermal comfort simulation using: - Simcenter STAR-CCM+ (.sim) for cabin airflow/temperature fields - TAITherm Human Thermal / HTE + Berkeley Comfort for occupant comfort outputs Task goal (what you need to deliver) We have a simplified cabin model. Under a cold ambient heating scenario, the current results are abnormal: occupant thermal sensation/comfort improves briefly and then becomes colder again (e.g., TS drops toward -1 and continues decreasing). We need you to diagnose the root cause and correct the model setup/coupling/mapping so the outputs are physically reasonable. Target requirements (high level): - Transient duration: 1800 s (30 min) - Monitoring temperatures: foot/foot-vent zone around ~35°C, head point around ~20°C (exact monitor definitions will be shared privately) - Comfort trend: overall thermal sensation & comfort must be normal/stable (after heating ramps up, it should not “get colder again”) What we expect from you - Identify why comfort trend becomes colder (typical causes include MRT/radiation boundary, incorrect field-to-human mapping of Ta/Tr/velocity/RH, initialization/restart issues, boundary leakage on cut surfaces, etc.) - Provide corrected settings + clear explanation of what was wrong and what you changed - Provide plots/outputs for monitoring temperatures + comfort metrics (TS/PMV/PPD or equivalent) Required experience (please do NOT apply if you don’t have this) - Hands-on experience with STAR-CCM+ transient cabin HVAC/thermal - Hands-on experience with TAITherm Human Thermal / Berkeley Comfort (not only CFD) - Ability to actually run the case (access to software/licenses or a workable setup) Confidentiality Due to confidentiality, we will share the detailed model files and full requirement document after you confirm capability. Please answer these in your proposal: 1) Have you used TAITherm Human Thermal / HTE + Berkeley Comfort in real projects? Share 1–2 lines of what you did (no confidential details). 2) Do you have access to STAR-CCM+ and TAITherm comfort/human modules to run the model? (Yes/No) 3) List your top 3 likely causes when cabin heating comfort “gets colder again” (keywords are fine: MRT/radiation, mapping, restart/initialization, boundary condition, cut-surface leakage, etc.) 4) What is your estimated time (days) to deliver corrected results + explanation? 5）Tell me how much you would charge for my task. —————————— Keywords: STAR-CCM+ .sim, Simcenter, cabin HVAC heating, automotive thermal management, TAITherm 2020, ThermAnalytics, Human Thermal Model, Human Modeling Extension (HTE), Berkeley Comfort Model, thermal sensation (TS), PMV, PPD, MRT (mean radiant temperature), radiation boundary, coupling/mapping, transient 1800s, monitoring points, HDF5 .tdf, .vfs .slf .tlf - Simcenter STAR-CCM+ (Transient / CHT / Radiation) - TAITherm / RadTherm (Human Thermal / HTE) - Thermal Comfort / Berkeley Comfort / PMV-PPD - Automotive HVAC / Cabin Thermal Management - CFD Post-processing / Data analysis (HDF5)

Flutter app - repost 2 due to christmas

ENGAGEMENT TYPE Hourly (Time & Materials) Estimated effort: 22–26 hours total Start: Immediate Level required: Senior / Very Senior Flutter Developer ONLY WHAT THIS JOB IS (READ CAREFULLY) This is a small, precise repair task in an existing Flutter app. There is no greenfield work involved. There will be: No new features No refactors No architecture changes No redesigns No experiments No “suggested improvements” No “I found another bug” unless it can be reproduced locally You are fixing known, clearly scoped issues only. IMPORTANT BACKEND & API CONTEXT (NON-NEGOTIABLE) All APIs and server-side code have been working as late as December 2025. A full Postman collection exists and can be executed at any time to verify API functionality. The backend is Magento 2.4. No backend work is required. No Magento developer work is required. Stripe APIs are live and working. This task is Flutter-only. Any attempt to reframe this as a backend, API, or Magento issue is incorrect. REQUIRED SKILL LEVEL (MANDATORY) You must be: A Senior or Very Senior Flutter developer Comfortable fixing Stripe and Apple Pay issues in production apps Able to read existing code and fix it without rewriting it Able to work independently without supervision If you are not senior, do not apply. NON-NEGOTIABLE ENGINEERING RULE Never update Flutter, packages, or plugins before the existing code is confirmed working. This is a basic rule, yet one that many so-called “senior” developers still get wrong. IMPORTANT CONTEXT (PLEASE READ) The app already compiles. A previous developer requested payment before automated tests were run. That is not acceptable under PPH standards. Testing comes first. Payment comes after. For this reason, the previous contract was terminated. This is shared for clarity so expectations are fully aligned. APPLICATION FILTERS (STRICT) If you present web pages as Flutter references, you are not of interest. If you have no verifiable references, you are not of interest. If you describe yourself as a “full-stack developer”, you are not of interest. If you over-explain, bloat, or try to over-engineer, you are not of interest. I am looking for a specialist, not someone who knows a little about everything. This is a razor-sharp task. Change existing code. Nothing more.
