What people complain about in Simulation & CAE
CAE simulations crashing and exhausting local hardware — 46 complaints across 19 products, 3 ideasEngineers running Ansys, Altair, and similar CAE tools consistently report crashes mid-analysis, lost work before saving, and simulations grinding to a halt because their local machines lack the RAM, GPU, or CPU to handle large models. Specific complaints include 'results mismatch when simulating the same design on different computers,' 'software defaults to only 4 cores regardless of hardware,' and 'crashes on load when opening complex CAD files' — problems that span every major vendor in the space, so no single vendor has an incentive to fix the infrastructure layer underneath.
Mesh creation that engineers can't control — 42 complaints across 10 products, 3 ideasEngineers across every major CAE package — Ansys Mechanical, HyperMesh, SimSolid, CFX — hit the same wall: auto-meshers produce results they can't inspect, can't trust, and can't fix without starting over. Complaints include 'I cannot see the mesh it is creating, so it is harder to trust that the simulation is accurate,' 'mesh cannot be controlled; you cannot tweak with the generated mesh,' and specific failures in hex meshing, sheet metal shell meshing, and 2D geometry that the built-in tools simply don't handle. The problem isn't that meshing is hard — it's that users have no meaningful feedback loop between the geometry, the mesher, and the result.
CAE software UI too hard to navigate — 40 complaints across 17 products, 3 ideasUsers across every major CAE product — Ansys, Altair, and others — describe interfaces that look and feel like they were designed in the early 2000s and have barely changed since. Complaints range from 'icons that are hard to find' and 'menus that overwhelm newcomers' to specific frustrations like LS-Prepost hanging and losing work, inconsistent behavior between Windows and Mac, and settings that are nearly impossible to locate without already being an expert. The core problem is not missing features — it's that the cognitive load of navigating these tools is high enough to slow down experienced engineers and genuinely block newer users.
Steep learning curve with no guided path — 24 complaints across 13 products, 3 ideasUsers across every Ansys product describe the same core problem: the software demands deep domain knowledge and software fluency simultaneously, and the training materials don't bridge that gap. Complaints range from 'learning resources from ANSYS are very limited and it's tough to utilize that knowledge in the actual simulation' to the software feeling like 'a black box — you put input on one end and get output on the other.' Specific workflows like coupling Ansys Mechanical with other modules, handling nonlinear problems with complex geometries, and setting up boundary conditions correctly are consistently called out as undocumented pain points that trap even experienced engineers.
Steep onboarding and fragmented workflow across Altair tools — 22 complaints across 7 products, 3 ideasNew and intermediate users consistently hit two walls: the tools take too long to learn without structured guidance ('all new users are often lost in the functionalities', 'hard to grasp what Altair Inspire is made for'), and the tools don't talk to each other cleanly once you do learn them — geometry imports break between versions, ANSA-to-Hypermesh transfers lose data, and the connection between Altair's own products is described as 'insufficient'. These aren't bugs users expect to be patched; they're structural friction that compounds every time a new engineer joins a team or a project crosses tool boundaries.
Nonlinear simulation convergence failures and opacity — 22 complaints across 7 products, 3 ideasEngineers across Altair and Ansys products repeatedly hit convergence failures in nonlinear analyses — contact problems, large deformation, separating contacts — with no guidance on why it failed or how to fix it. Users describe 'failed convergence happening way too much' with no auto-optimization for contact stiffness or other solver parameters, and note that nonlinear accuracy is visibly weaker than Abaqus, especially for assemblies with general contact. The frustration isn't just that it fails — it's that when it fails, the software offers almost nothing to help the engineer understand or recover.
CAE solver errors that tell you nothing — 20 complaints across 8 products, 3 ideasEngineers running FEA and CFD analyses repeatedly hit solver failures with no useful error messages, or get cryptic intermediate output that tells them nothing about what broke or where. Several complaints point to the same pattern: 'the solver can fail during complex analyses without generating an error code,' 'the error messages the solver gives are not particularly helpful for solving issues,' and understanding what went wrong from intermediate results is described as outright difficult. When you're running a multi-hour solve on a large model, a silent failure or a generic error wastes an entire run and often a full working day.
CAE software too expensive to access flexibly — 17 complaints across 12 products, 3 ideasEngineers, students, and small teams are priced out of major CAE tools because licenses are sold as expensive perpetual or annual seats with no pay-as-you-go option. Users specifically complain that 'every tool requires a license, making it very expensive,' that nominative licensing makes it impossible to share seats across a team, and that students lose access entirely after graduating. The result is that people who could be productive users — freelancers, researchers, small consultancies — simply can't get in.
