I will perform structural fea and multi load stress analysis
K. Witthawat
About this gig
Need to mathematically verify if your mechanical or composite component can handle complex operational loads? I perform high-fidelity Structural FEA (Finite Element Analysis) for single parts using SimScale (CalculiX) and ANSYS Mechanical. Prevent structural failure and optimize weight.
ACCURACY BENCHMARKS (Case Study: FWA_001A Wishbone):
Structural Integrity: Stress mapped up to P95 limits vs CFRP UTS.
Singularity Management: Isolated numerical singularities for design accuracy.
Stability: Verified stability with Euler buckling load factor (Lambda).
PACKAGES:
BASIC ($35 | 3 Days): 1 material, 1 static load case FEA. Deliverable high resolution result images and 1-2 PDF report.
STANDARD ($100 | 5 Days): 1 material, 2-3 operational load cases for moderate parts. Deliverable images and 3-5 PDF report.
PREMIUM ($150 | 7 Days): Complex components (like wishbones) and 5-7 page comprehensive PDF report.
REQUIREMENTS: STEP/IGES/STL file, load cases (forces/moments), constraints, material properties.
NOTE: Strictly 1-part analysis. No CAD modification. CONTACT ME BEFORE ORDERING!

Professional CAE Engineer | Validated FEA & Thermal Simulations
About Me:
I’m a Manufacturing Engineer (Automotive & Aerospace) from KMUTT. I help hardware teams verify designs using research-driven CAE (40+ sources/project). I specialize in high-fidelity FEA via FreeCAD and SimScale.
What I offer:
• Academic Precision: Physics-based BC derivation.
• Reliability: Mesh sensitivity & solver convergence focus.
• Documentation: 15-20+ page engineering dossiers.
Expertise:
• Thermal Management (Brakes)
• Composite Structural FEA (CFRP)
• Static Linear Simulations
• Technical Research Reports
FAQ
Q1: What CAD file formats do you accept?
A: I accept STEP, IGES, and STL formats. To ensure mathematical accuracy, please ensure the geometry represents a single component rather than a massive assembly.
Q2: Will I receive the simulation source files?
All packages deliver comprehensive engineering PDF reports and stress contour plots. Full access to the verified SimScale setup is available as a Gig Extra for $20.
Q3: Can you analyze composite materials like carbon fiber (CFRP)?
A: Yes. I perform orthotropic material modeling for composites (e.g., F1-style hybrid CFRP setups) evaluating ply failure criteria under the Premium package.
Q4: How do you handle stress concentrations or singularities?
A: I employ advanced numerical singularity management to isolate artificial stress concentrations from sharp geometric constraints, ensuring real-world safety margins.
Q5: Can you analyze large structural assemblies or modify my CAD?
A: No. This gig focuses strictly on validation, structural simulation, and reporting for a single component. Complete CAD design modifications or assemblies are not included.
