'trial calculation' is a correct and usable phrase in written English.
It is used to describe a calculation done as part of a test or experiment to see if something works. For example, "We will need to do a trial calculation to make sure our new method of measuring the area is accurate."

A trial calculation method for the different models is adopted so as to obtain the most suitable rheological model and corresponding parameters.
Newton Raphson algorithm, which regarded the contact angle as the iteration variable, was proposed to calculate the heat power and stiffness of bearings and improve the convergence of the algorithm, and the termination criteria of contact angle's searching trial calculation was proposed to improve the accuracy of the algorithm.
Table 1 shows the main statistical parameters of the trial calculation.
In addition, using the outputs of our model in a generic sample size calculation we found large differences in the required sample size between the POPI trial calculation and our model prediction.
Estimated PGAs and parameters of fault models used in the trial calculations.
Derivatives of natural frequencies and mode shapes are determined after two trial calculations of the equation.
In practice, multiple threshold values are needed and trial calculations are performed to determine the appropriate threshold level.
We have confirmed by trial calculations that B < A leads to weak coupling during interseismic periods, and B > A leads to spontaneous occurrence of slow slip events (corresponding to the result by Yoshida and Kato (2003)).
Environmental controls on the life cycle of Priobium spp. are poorly known, but trial calculations would suggest that dates could easily occur a week or two earlier by the end of the century.
Trial calculations performed for the DCT II, DCT I, biorthogonal DCT I, Haar and Walsh transforms show that the results are very close to those predicted by the model.
