Geometry & boundaries
What is being assessed?
Drawings, CAD, dimensions, supports, interfaces, known constraints and relevant simplifications.
Services
Thermal, Cryogenic & Coupled Simulation
Transient heat-transfer and thermo-mechanical simulation for structures and industrial systems where temperature history, thermal gradients, phase-related heat transfer or restraint govern structural response.
Buyer problem
Transient temperature · thermal gradients · thermal shock · structural response
Thermal loading is rarely defined by one temperature value. Exposure history, boundary heat transfer, affected area, duration, material-temperature dependence, restraint and the transition between hot and cold regions can govern the resulting structural demand.
Method
The workflow may use prescribed-temperature screening, transient heat transfer, film or flux boundaries where supported by data, sequential thermal-to-structural mapping, temperature-dependent properties and structural response assessment.
Deliverable
Temperature histories, spatial gradients, thermal stress/deformation, critical-zone interpretation, boundary-condition comparison and a report documenting exposure assumptions and limitations.
Value
The service separates the thermal physics from the structural consequence and identifies whether gradients, local cooling or restraint — rather than minimum temperature alone — control the response.
Typical inputs
What we need to scope this service.
Materials & loading
What controls the physics?
Material grade/data, preload or operating state, load history, pressure, temperature, impact/blast scenario or other relevant actions.
Decision objective
What must the analysis answer?
Local demand, failure mechanism, comparison, screening, residual response, retrofit effect, integrity concern or report requirement.
Technical depth
How Axis scopes the analysis.
01
When this service is needed
Use this service when rapid heating/cooling, cryogenic exposure, thermal shock, nonuniform temperature fields or coupled thermal–structural behaviour may govern tanks, shells, supports, piping-related details, concrete containment or other structures.
02
Modelling depth
The modelling depth is matched to available heat-transfer data: from bounded screening cases to transient thermal analysis and mapped thermo-mechanical response. Fracture-oriented follow-on methods can be added where justified.
03
Verification controls
Thermal boundary assumptions, temperature histories, spatial gradients, mapped-field consistency, temperature-dependent properties, support restraint and stress histories are reviewed.
04
Client value
Clients can understand which part of the thermal scenario drives structural demand and what additional data or follow-on integrity assessment is justified.
Typical inputs
- Geometry, wall/support detail and relevant thermal interfaces
- Exposure temperature, fluid/process information and duration
- Heat-transfer or boundary-condition data where available
- Temperature-dependent material properties where available
- Required outputs: temperature, stress, deformation, damage/fracture indicator or report
Scoping principle: the modelling level is selected after reviewing the engineering question, available data, uncertainty, and required decision. Axis does not recommend high-complexity simulation when a simpler verified check is more appropriate.
