Error in dynare (line 235) evalin('base',fname)

First of all, do not loop over stoch_simul and resol. You only need the latter. In particular, you are not supposed to loop over Dynare syntax, only over the calls to Matlab functions.
You need to condition on the error code returned by resol, i.e. the content of info. It will tell you if the BK conditions are satisfied or not. You can see all cases in print_info.m:

      case 3
        error(['Blanchard Kahn conditions are not satisfied: no stable' ...
               ' equilibrium'])
      case 4
        error(['Blanchard Kahn conditions are not satisfied:' ...
               ' indeterminacy'])
      case 5
        error(['Blanchard Kahn conditions are not satisfied:' ...
               ' indeterminacy due to rank failure'])

The problem you experience is that you are trying to read out a decision rule coefficient, but the model does not have a solution. So the decision rule you are trying to access does not exist.

 * This file replicates the model studied in:
 * Ascari, Guido and Sbordone, Argia M. (2014): "The Macroeconomics of Trend Inflation",
 * Journal of Economic Literature, 52(3), pp. 679-739.
 * 
 * It provides a replication of the main results of the original paper  
 * in Section 3 (the New Keynesian model with trend inflation). It replicates the Figures:
 * - Figure 7: The Cost of Price dispersion
 * - Figure 8: Trend Inflation and Steady State Variables
 * - Figure 11: The Determinacy Region and Trend Inflation
 * - Figure 13: Impulse Response Functions to a 1 Percent Positive Technology Shock 
 * - Figure 14: Impulse Response Functions to a 1 Percent Positive Monetary Policy Shock 
 *
 * Moreover, it replicates the business cycle moments reported on p. 717. 
 *
 * This mod-file shows how to access steady state variables in order to plot steady state
 * dependences on parameters.
 * It also shows how to manually do a stability mapping be iterating over a grid on the parameter space.
