# Operations reports and developer utilities

Choose a defined job, review its input example and price, then select a payment option. Private result access lasts30days; save your downloaded copy. Each is a one-time job, without a recurring commitment. Use authorized, non-sensitive input. The work is limited to the supplied records or mathematical profile, without external actions, professional certification or an outcome guarantee. Input and computation profiles describe the work included, not payment admission limits. A quote is unpaid; a signature alone does not establish settlement.

## Reciprocal Electrohydrodynamic Open Circuit

USD 1.00 per job.

Solve zero electrical current for a supplied symmetric positive-definite2x2 Onsager flow/current matrix. Drive signs and units must be conjugate to flows; no inferred channel coefficients or active circuit action. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.

## Electroneutral Zero Current Diffusion Flux

USD 1.00 per job.

Local ideal Nernst-Planck diffusion fluxes and diffusion electric field under electroneutral composition/gradient and zero total charge current. Positive field drives cations forward. Distinct from conductivity: requires concentration gradients and solves the coupled no-current constraint. No electrode, imposed flow or concentrated-solution correction. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.
